Why ionic tabs are not rendered properly?

Question

I am new to ionic(although I have some knowledge of angularJs). I am facing problem in ion-tabs. Following is my code :-

// Ionic Starter App

// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
angular.module('starter', ['ionic'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    if(window.cordova && window.cordova.plugins.Keyboard) {
      // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
      // for form inputs)
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

      // Don't remove this line unless you know what you are doing. It stops the viewport
      // from snapping when text inputs are focused. Ionic handles this internally for
      // a much nicer keyboard experience.
      cordova.plugins.Keyboard.disableScroll(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();
    }
  });
})
.config(function($stateProvider, $urlRouterProvider){
	$urlRouterProvider.otherwise('/home');
    
    $stateProvider
        
        // HOME STATES AND NESTED VIEWS ========================================
        .state('home', {
            url: '/home',
            views: {
                '': {
                    templateUrl: 'partial-home.html'   
						},
                'other@home': {
                    template: "Hello World! I am other-11."
                },
                'other': {
                    template: "Hello World! I am other 12."
                }
            }
        })
        
        // nested list with custom controller
        .state('home.list', {
            url: '/list',
            templateUrl: 'partial-home-list.html',
            controller: function($scope) {
                $scope.dogs = ['Bernese', 'Husky', 'Goldendoodle'];
            }
        })
        
        // nested list with just some random string data
        .state('home.paragraph', {
            url: '/paragraph',
            template: '<ion-view view-title="paragraph">I could sure use a drink right now.</ion-view>'
        })
});

		</ion-nav-buttons>
	</ion-nav-bar>
	<ion-nav-view>
	</ion-nav-view>
  </body>
</html>

It renders following output :-

Following are the problems, that I am facing :- 1) Although, tabs are appearing, but when I click on individual tab, it's internal content is not getting populated with current code(that I have posted) and navbar title is also not changing, in spite of view-title property being set in each child state template.

2) In partial-home.html template in html code, I want navbar to have some extra buttons in it, but those buttons are also not getting shown.

3) However, when I change partial-home.html, to something given below(I have removed name property from ion-nav-view),

<script type="text/ng-template" id="partial-home.html">
		<ion-view view-title="def" hide-nav-bar="false" class="padding padding-vertical"> 
			<ion-nav-buttons side="right">
				<button class="button button-icon ion-home"></button>
				<button class="button button-icon ion-ios-email"></button>
				<button class="button button-icon ion-ios-person"></button>
			</ion-nav-buttons>
			<ion-tabs class="tabs-icon-top">
				<ion-tab title="list" icon="icon ion-home" href="#/home/list">
					<ion-nav-view></ion-nav-view>
				</ion-tab>
				<ion-tab title="paragraph" icon="icon ion-heart" href="#/home/paragraph">
					<ion-nav-view></ion-nav-view>
				</ion-tab>
			</ion-tabs>
		</ion-view>
	</script>

then, tab contents are appearing properly, when I click on individual tab, but tab content appears behind navbar, as shown in image given below :-

I don't know, where I am going wrong. Thanks in advance.

Hello @varunaaruru, I am unknown to plunker/codepen. Can you create the same, if possible ? — Mangu Singh Rajpurohit
i dont know why you are using that complex structure to create and navigate tabs.. checkout this plunker embed.plnkr.co/B9ORrv — varun aaruru

Dont use script tags to create different tab pages . I suggest you to download starter tabs template and look into that

Ionic start appname tabs

for navbar buttons include this code in the page where you want the buttons.

`

<ion-nav-buttons side="right">
  <button class="button" ng-click="doSomething()">doSomething</button>
 </ion-nav-buttons>

The side to place the buttons in the ionNavBar. Available sides: primary, secondary, left, and right.

If content goes behind navigation bar, write this in <ion-content>

<ion-content has-header="true">
