I am developing an android app using ionic framewrok ,in this the toggle menu is missing when back from another page.

This is defalut view

home.html

<ion-view hide-back-button="true"  view-title="HOME">
	<ion-nav-buttons side="left">
		<button menu-toggle="left" class="button button-icon icon ion-navicon"></button>
	</ion-nav-buttons>
	<ion-content class="has-header text-center">
		<div class="row nopadding">
			<div class="col nopadding"><img src="img/home_icon/top.jpg" width="100%"></div>
		</div>
		<div class="row nopadding">
			<div class="col nopadding"><a href="#/app/notes"><img src="img/home_icon/about.jpg" width="100%"></a></div>
			<div class="col nopadding"><a href="#app/culture"><img src="img/home_icon/kerala.jpg" width="100%"></a></div>
		</div>       
	</ion-content>
</ion-view>

when user clicks on about.jpg it will go to notes.html

notes.html

<ion-view view-title="Notes">
  <ion-content>
    <h1>Notes</h1>
    <div class="card">
  <div class="item item-text-wrap">
    This is a basic Card which contains an item that has wrapping text.
    <a href="#/app/note-details">Details</a>
  </div>
</div>
<div class="card">
  <div class="item item-text-wrap">
    This is a basic Card which contains an item that has wrapping text.

  </div>
</div>
  </ion-content>
</ion-view>

Here is app.js

.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider

    .state('app', {
    url: '/app',
    abstract: true,
    templateUrl: 'templates/menu.html',
    controller: 'AppCtrl'
  })
  .state('app.notes', {
    url: '/notes',
    views: {
      'menuContent': {
        templateUrl: 'templates/notes.html'
      }
    }
  })
    .state('app.home', {
      url: '/home',
      views: {
        'menuContent': {
          templateUrl: 'templates/home.html',
          controller: 'HomeCtrl'
        }
      }
    })
  // if none of the above states are matched, use this as the fallback
  $urlRouterProvider.otherwise('/app/home');
});

when i press the backbutton from notes.hml page it navigate back to the home.html but the toggle menu is missing untill the refresh.

How to solve this probelm??
