Navigation view is not working in Ion-tab

Hi,
I created login page and displaying ion tab page when i click on login button.
I used ion-nav-view in each tab and below code but below code is not working for tab naivigation.

.state('dash', {
	url: '/dash',
	views: {
	  'tab-dash': {
		templateUrl: 'templates/personal.html',
		controller: 'DashCtrl'
	  }
	}
})

Please suggest me what could be the wrong.
