AccountCtrl logout not working as a button on nav

[yipcma]

Hello, I have been trying to make a logout button to be on a nav bar and control its showing using ng-show-auth. However, when i click the button after login, it doesn't do anything.

Could someone shed some light on the matter?

my AccountCtrl and LoginCtrl are as in the generated project. My navbar looks like this:

  <div ng-controller="LoginCtrl" class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
    <ul class="nav navbar-nav navbar-right">
      <li>
        <a ng-href="#">Home</a>
      </li>
      <li>
        <button class="btn btn-primary" ng-hide-auth="" ng-click="oauthLogin('facebook')">Facebook</button>
        <button ng-controller="AccountCtrl" ng-show-auth="" role="button" ng-click="logout()" class="btn btn-danger">Log Out</button>
      </li>
    </ul>
    <p ng-show="err" class="bg-danger">{{err}}</p>
  </div><!-- /.navbar-collapse -->
  </nav>

and my index.html reference for nav.html:

    <!-- Add your site or application content here -->
    <div class="container">
      <div class="header" ng-include="'views/nav.html'"></div>

      <div ng-view=""></div>

Thank you so much in advance.
