Ionic - routing issue/button link -

-

i'm writing first ionic app , hit little problem.

i have tab interface has login screen, once login can select tabs, on 1 tab screen have list of items need click show further options, can't quite these links work, think ui-sref bit wrong... looking second pair of eyes! linking profile view i'm struggling with, below app.js routing , page links on below.

app.js .state('login', { url: '/login', templateurl: 'templates/login.html', controller:'loginctrl'

})

 // setup abstract state tabs directive   .state('tab', {   url: "/tab",   abstract: true,   templateurl: "templates/tabs.html"   })  .state('tab.profile', { url: '/profile', views: {   'profile': {     templateurl: 'templates.tab.profile.html',     controller: 'profilectrl'   } }

})

then list page:

 <ion-content has-header="true" padding="true" class="viewer-panel">          <div class="list">             <div class="item item-divider">             profile           </div>               <a class="item item-icon-left" ui-sref="tab.profile">                 <i class="icon ion-person"></i>                 view profile               </a>
