Ionic tab does not route to correct view

For some reason one of my tabs(the chat tab) doesn’t work. All the other tabs work i’m not sure why the chat tab doesn’t work. As you can see from my plunker the chats tab is just blank while the other tabs show content. In my actual app the title bar shows but has the text of the previous tab.

So heres my plunker:

Heres some code:

index.html:

<!DOCTYPE html>
<html>

<head>
  <meta http-equiv="content-type" content="text/html; charset=UTF-8">
  <title></title>

  // Ionic uses AngularUI Router which uses the concept of states
  // Learn more here: https://github.com/angular-ui/ui-router

    abstract: true,

  // Each tab has its own nav history stack:

    .state('tab.chat-detail', {

    }

  // if none of the above states are matched, use this as the fallback
  $urlRouterProvider.otherwise('/tab/dash');

});

Thanks.

EDIT:

Named the chat file in the plunker incorrectly. Changed the name of Chat.html to Chats.html. It still does not work however, here is the new plunker:

.state('tab.chats', { url: '/chats', views: { 'tab-chats': { templateUrl: 'tab-chats.html', controller: 'ChatsCtrl' } } })

you don’t have tab-chats.html, replace that with tab-chat.html and see the result.

you can check this types of errors via console log in chrome.
