title: ng-show not showing with variable check
body: <p>This is my controller:</p>
  
  <pre><code>capApp.controller('cookieCtrl', ['$scope','$cookies', function($scope, $cookies) {
    var cookieSet = $cookies.user_id;
    alert('coolkie is ' + cookieSet); // this is fine and shows the value
  }]);
  </code></pre>
  
  <p>And the nav I want to show:</p>
  
  <pre><code>&lt;div id="siteNav2" ng-controller="cookieCtrl"&gt;
    &lt;nav class="navbar navbar-inverse navbar-fixed-top" ng-show="cookieSet"&gt;
      ... all nav here ...
    &lt;/nav&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>But it shows, then disappears...</p>
  
  <p>I also tried, but same result:</p>
  
  <pre><code>ng-show="cookieSet != null"
  </code></pre>
