Data Binding is not updating Angular JS - angularjs

I am really new in AngularJS but I have to make a web app using it, I have some input that control the style of an element (width, height, name, description and color) on the left side of my HTML. I used to had all elements hidden, when the user clicked it appeared and everything worked good, now I started using ui-router, if you click the 'Fullscreen' it will call thet html file. Some inputs work except the one I defined an initial scope value.
I leave a plunker so you can have an idea of what's going on.

Router creates new myCtrl instance with it's own scope. You can create service to share data between two controllers or create another controller type for /fullscreen.

This is the controller.
'use strict';
angular.module('myContacts.contacts', ['ngRoute','firebase'])
.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/contacts', {
templateUrl: 'contacts/contacts.html',
controller: 'contactsCtrl'
});
}])
.controller('contactsCtrl', ['$scope', '$firebaseArray', function($scope,$firebaseArray) {
var ref = new Firebase('https://mycontacts-1bb2d.firebaseio.com/contacts');
$scope.contacts = $firebaseArray(ref);
$scope.showAddForm = function(){
$scope.addFormShow = true;
}
}]);
This is pretty simple code. Its supposed to show the form when the user clicks on the '+' button. But I cant figure out why the ng-show directive is not working.

It works fine with your code, check if you have properly added ng-controller in your code.
DEMO
var myApp = angular.module('ReqWebApp', [])
myApp.controller('contactsCtrl', function contactsCtrl($scope) {
$scope.showAddForm = function(){
$scope.addFormShow = true;
}
});

<div class="small-12 large-2 columns">

The code works fine for me. I think you might have done some small error in adding controller. Refer the code below
<html ng-app='FormApp'>

<form ng-show="addFormShow">

How to create ng-model array with ng-repeat(number)

I have 2 step form
on step 1 : ask user to how many input form needed
that use in < input type="number" ng-model="vm.nkeys" />`
on step 2 : want to create one input text for each with ng-model and name attribute in array form so that I can capture the every input box value; but both is not working; see the relevant code and wokrking plunker below.
<div ng-show="vm.step == 2" ng-form="vm.step2form" class="step-content body" >
<div class="text-center m-t-md">
<div ng-repeat="n in [].constructor(vm.nkeys) track by $index" class="form-group">
<label class="col-sm-2 control-label">{{$index+1}}</label>
<input ng-model="key_desc" name="description_{{n}}" type="text" class="form-control" >
</div>
</div>
</div>
tried ng-model="key_desc[{{$index+1}}] but no success; also name=description_{{$index}} is also not working
see the demo plunker
what do I need to do?

Have a look at the sample snippet below:
<div ng-repeat="item in getNumber(key) track by $index">
<input type="text" ng-model="text[$index]" name="input_{{$index}}" />
<span ng-if="text[$index]">
- {{text[$index]}}
</span>
</div>
Refer the demo here.
See your code now:
<div ng-repeat="n in vm.getNumber(vm.nkeys) track by $index" class="form-group">
<!-- Other stuff -->
<input id="location" ng-model="key_desc[$index]" name="description_{{n}}" type="text" class="form-control" >
</div>
See you code here.

Try this
<input ng-model="key_desc['{{$index}}']" name="description_{{n}}" type="text" class="form-control" >

Set vm variable to ng-model.
(function () {
'user strict';
angular.module('app',[])
.controller('FormController', function ($log) {
var vm = this;
vm.title = 'Key Manager';
vm.step = 1;
vm.key_desc = [];
vm.submit = _submit;
function _submit(){
alert(vm.key_desc);
}
vm.next = function() {
$log.debug('clicked on next');
if(vm.step < 3 )
vm.step = vm.step + 1;
vm.getKeys=function(n){
return new Array(n);
};
}
vm.prev = function() {
$log.debug('clicked on prev');
if(vm.step > 0)
vm.step = vm.step - 1;
}
vm.hasPreviousStep = function(){
var previousStep = vm.step - 1;
return (previousStep > 0);
};
});
})();

model name could be connect with controller name..using vm variable..
In your controller initialize vm.key_desc = [] in your controller..

Use an Array element as ng-model
<input ng-model="key_desc[$index]" name="description_{{n}}"
type="text" class="form-control" >
here the value of first input will be in $scope.key_desc[0], second in $scope.key_desc[1] and so on
before that, initialise $scope.key_desc = [] in your controller

Angular Controller not found

Problem Definition
I am using AngularJS's ngRoute module for the first time and I am running into some trouble with it. I have a index.cshtml page in which I reference my routingModule by setting the ng-app. I also have a ng-view so that when I click on "New Account" it loads register.cshtml in the ng-view or if I click on "Sign In" it will load authenticate.cshtml in the ng-view.
The routing is working as expected since I can see the register and authenticate pages load in the ng-view when I click the links in on my index page. But the controllers I have set for the register and authenticate pages in the routingModule.js seem to not be there.
I get this error when clicking on "New Account" on the index page.
I get the same error when I click on "Sign In" on the index page
I have added all the javascript and html files below needed to solve the problem. Any help would be much appreciated.

From what i can see here, the authenticationModule and registerModule are missing as dependencies of your routingModule:
var routingModule = angular.module("routingModule", ['ngRoute', 'authenticationModule', 'registerModule'])

Unable to determine why form won't submit

I've created a basic angular form and can't determine why it's not submitting.

My Controller:
<script type="text/javascript">
angular.module('contact', []).
controller('myController', function ($scope) {
$scope.debug = function () {
console.log($scope.form);
}
});
</script>

I think you just need to specify the action explicitly, not with an empty string otherwise angular will prevent the submission.

How to hide and show a div, based on model condition in angularjs?

I want to hide/show a div based on checkbox. Seems pretty simple. I store the value of checkbox in a model and use it in div ng-show. What am I doing wrong?
<div ng-app='visibleApp'>
<div ng-controller='myController'>
<input type="checkbox" name="hideBasicInfo" ng-model="hideBasicInfo">hide the basic information section
<div ng-show="{{!hideBasicInfo}}">
<label for="firstName">First Name:</label>
<input type="text" name="firstName" ng-model="firstName"/></br>
<label for="middleName">Middle Name:</label>
<input type="text" name="middleName" ng-model="middleName"/></br>
<label for="lastName">Last Name:</label>
<input type="text" name="lastName" ng-model="lastName"/>
</div>
<hr/>
<div>
<h4>Debug Information</h4>
hideBasicInfo: {{hideBasicInfo}}<br/>
!hideBasicInfo: {{!hideBasicInfo}}
</div>
</div>
</div>
JS file:
var visibleApp = angular.module('visibleApp',[]);
visibleApp.controller('myController', function($scope){
$scope.data = "my data";
$scope.hideBasicInfo = false;
});
Thank you.
See fiddle

almost there...
<div ng-hide="hideBasicInfo">
...
</div>
no template braces ( {{}} ) needed.

<div ng-show='One'>
<p>Section One</p>
</div>
<div ng-show='Two'>
<p>Section Two</p>
</div>
<div ng-show='Three'>
<p>Section Three</p>
</div>
<!-- Navigation -->
<nav>
<a href='#' ng-click='showOne'> Show Div One </a>
<a href='#' ng-click='showTwo'> Show Div Two </a>
<a href='#' ng-click='showThree'> Show Div Three </a>
</nav>
