You did wrong in your embedded html. I changed your source code to:
template:'<div>User Name<input type="text" ng-model="reg.Username" name="Username" class="form-control" required ng-minlength="5" ng-maxlength="20" /></b></div>' +
'<br><div ng-messages="regForm.Username.$error" style="color:maroon" role="alert">' +
'<div ng-message="required">Enter User Name</div>' +
'<div ng-message="minlength">User name is too short</div>' +
'<div ng-message="maxlength">User Name is too long</div></div>',
And it worked here: http://plnkr.co/edit/onlfdhraHipjezcgIg7f?p=preview

I am trying to create a link where I click the register button and it goes onto the register.html, without it needing for the page to start reloading. But when I click the register link, nothing seems to happen when I click it.
index.html:
<!DOCTYPE html >
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>

<label for="login">Login</label>
<input id="login" ng-model="login" type="text">

<label for="password">Password</label>
<input id="password" ng-model="password" type="text">
<br>
<button type="button" ng-click="login()">Login</button>
<a href="#!register" >Register</a>
<div ng-view></div>
</body>
</html>
app.js:
var app=angular.module("myApp",["ngRoute"]);
app.config(function ($routeProvider) {
$routeProvider
.when("/",{
templateUrl:"index.html",
})
.when("/register",{
templateUrl:"register.html",
controller:"Registration"
});
})
app.controller('Login',['$scope', function ($scope) {
}])
app.controller("Registration", function ($scope) {
$scope.msg = "I love London";
});
register.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<h1>Registration page</h1>
</head>
<body ng-app="myApp" ng-controller="Registration">

</html>
You should fix your link to:
Register
Check documentation for details $route#examples
i have this peace of code in angularjs:
<div ng-repeat="item in benchmarGeographyObj">
<div style="padding-right: 60px;float:left;">
<input readonly style="width: 100%;" type="text" id="unik" ng-value="item.BEN_BENCHMARK_GEOGRAPHY" />
</div>
</div>
The Problem when i try to add ng-model in the input text, the value of ng-value disappeared, how i can fix this proble please ?
From the ngValue reference:
It can also be used to achieve one-way binding of a given expression
to an input element such as an input[text] or a textarea, when that
element does not use ngModel.
https://docs.angularjs.org/api/ng/directive/ngValue
This means you have to use either ngModel or ngValue, but not both. They conflict.
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
$scope.benchmarGeographyObj = [{'BEN_BENCHMARK_GEOGRAPHY': 1},{'BEN_BENCHMARK_GEOGRAPHY': 2}];
});

I've been trying to find a for solution for this for hours and I just can't find any.
My problem is that the data binding suddenly isn't working after I put ng-app="myApp" in my Html tag. However, when I put it this way: ng-app="", the data binding is already working. Can you guys figure out why angularjs data-binding is not working after I put or identify "myApp" in my ng-app?
var app = angular.module('myApp'. []);
This should have a comma and not a dot
var app = angular.module('myApp', []);
Also add ng-controller="myCtrl" to your view
you should add ng-controller directive to your view.
<body ng-controller="myCtrl">
<div class="container">
<input class="form-control" ng-model="Firstname" />
{{Firstname}}
</div> <!-- container -->

Today is the first when i started reading about Angular JS and I tried to do a very basic thing after reading from a tutorial.
<!DOCTYPE html>
<html data-ng-app="">
<head>
<title></title>
</head>
<body>
Name:
<br />
<input type="text" data-ng-app="name" /> {{ name }}
<script src="Scripts/angular.min.js" type="text/javascript"></script>
</body>
</html>
I downloaded and added the angular js library from GitHUB 1.4.x(latest). I expect the name to be written on the fly when user types in the textbox but nothing happens. What am i missing for this basic set up ?
P.S. - I am using an HTML page in Visual Studio 2010.
Some minor adjustments to your code, and it works just fine:
<html ng-app="">
<head>
<title></title>
</head>
<body>
Name:
<br />
<input type="text" ng-model="name" /> {{ name }}
<script src="Scripts/angular.min.js" type="text/javascript"></script>
</body>
</html>
A working code pen can be seen here: http://codepen.io/anon/pen/jPWyaR
JSFIDDLE http://jsfiddle.net/seadonk/aze39fjq/
change the html tag to: <html ng-app>
change your input directive to data-ng-model="name"
<html ng-app>
<head>
</head>
<body>
Name:
<br />
<input type="text" data-ng-model="name" /> {{ name }}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
</body>
</html>
I note a few things.
a) No reference to script file which should contain an angular module declaration.
b) The input references an angular app named "name" but it is immediately closed
c) No controller declared
d) data-ng-app needs older version of angular. I suggest use 1.3.5
I will do the following corrections to get it working.

i have routeProvider, ng-view and controller.
Simple template with form and input. I can see $dirty value in {{form.var1.$dirty}} - it changes when i type, but how to access it in the controller code?

check dirty

</form>
js
angular.module('project',[]).
config(function($routeProvider) {
$routeProvider.
when('/', {controller:Ctrl1, templateUrl:'dirty_tab.html'}).
when('/tab1', {controller:Ctrl1, templateUrl:'dirty_tab.html'}).
otherwise({redirectTo:'/'});
});
function Ctrl1($scope,$rootScope) {
$scope.var1=100;
$scope.dodo1 = function() {
alert(form.var1.$dirty);
}
}
Alert shows me "undefined".
How to get var1 $dirty value?
As Cherniv told you in the comments you need to access the variable from the $scope object
$scope.form.var1.$dirty
