Angularjs ui-bootstrap datepicker is not working in my application - angularjs

Question

Here is code which I am to trying to run in my application. Even I have the same versions of js and css. here is the plunker link. demo of original code, here.
//html code
<div ng-controller="DatepickerDemoCtrl">
<h4>Popup</h4>
<div class="row">
<div class="col-md-6">
<p class="input-group">
<input type="text" class="form-control" datepicker-popup="yyyy-MM-dd" ng-model="dt" is-open="opened" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open($event)"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
</div>
</div>
//Js code
var DatepickerDemoCtrl = function ($scope) {
$scope.open = function($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened = true;
};
};
This code I have applied exactly same in my controller, I have included dependency modules also, I have same versions as in plunker. but is not working in my application. I am struggling from last 2 days. Please somebody let me know the reason.
Here is my html
<h4>Popup</h4>
<div class="row">
<div class="col-md-6">
<p class="input-group">
<input type="text" class="form-control" datepicker-popup="yyyy-MM-dd" ng-model="dt" is-open="opened" />hi{{dt}}
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="opencal($event)"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
</div>
....//my ctrl is home ctrl here so this code wrapped in homectl.
Here is my js code
//app code.
var app1 = angular.module("HomeApp",['uiSlider','ui.bootstrap']);
//this where i defined dependency.
app1.controller('HomeCtrl', function( $scope,$http,$q,$location,$window,$routeParams,$modal, $log) {
//here is my datepicker code.
$scope.opencal = function($event) {
$event.preventDefault();
$event.stopPropagation();
$scope.opened = true;
};
...//my rest code goes below
Queries I have is
I cant see date when I select date from calendar.(in {{dt}}).
I need to pass selected date to my home controller.
