Help with menu and tabs

ionic-v1

I have a app with left menu. Now I want to change one of by pages to contain tabs. This causes me a lot of problems. So I need some extras eyes on what I am doing wrong.

In my app.js here is a part of my configuration:
.state(‘app’, {
url: ‘/app’,
abstract: true,
templateUrl: ‘templates/menu.html’,
controller: ‘AppController’
})

.state('app.userlist', {
    url: '/userlist',
    cache: false,
    views: {
        'menuContent': {
            templateUrl: 'templates/userlist.html',
            controller: 'UserListController'
        }
    }
})

.state('app.supscription', {
    url: '/subscription',
    abstract: true,
    views: {
        'menuContent': {
          templateUrl: 'templates/subscriptionTabs.html'
        }
    }
})

I want the subscription page to contain tabs.
if I do not use views with menuContent the subscription page is blank.
The subscriptionTabs.html look like this:

<ion-tabs class="tabs-icon-top tabs-positive">
  <ion-tab title="Names" icon="ion-home" href="#/subscription/names">
    <ion-nav-view name="subscriptionTab"></ion-nav-view>
  </ion-tab>
  <ion-tab title="Types" icon="ion-ios7-information" href="#/subscription/types">
    <ion-nav-view name="subscriptionTab"></ion-nav-view>
  </ion-tab>
</ion-tabs>

and the first page names is defined like this:

<ion-view view-title="Subscription Names">
       <ion-content class="has-header">
         <div class="card">
           <div class="item item-text-wrap">
             subscription names
           </div>
        </div>
        </ion-content>
</ion-view>

in the app.js the tab pages are configured in this way:

.state('app.supscriptionNames', {
    url: '/names',
    views: {
        'subscriptionTab': {
            templateUrl: 'templates/subscriptionNames.html',
            controller: 'HelpController'
        }
    }
})

.state('app.supscriptionTypes', {
    url: '/types',
    views: {
        'subscriptionTab': {
            templateUrl: 'templates/subscriptionTypes.html',
            controller: 'HelpController'
        }
    }
})

When running the console and server log do not shows any errors.
