title: ng-show on AngularJS alert
body: <p>I am trying to display some alerts with AngularJS, see <a href="http://angular-ui.github.io/bootstrap/" rel="nofollow">http://angular-ui.github.io/bootstrap/</a> - alert section.
  I want to modify the example to show only the alerts that have a "show" attribute set to true:</p>
  
  <pre><code>  $scope.alerts = [
      { type: 'error', msg: 'Oh snap! Change a few things up and try submitting again.', show: true }, 
      { type: 'success', msg: 'Well done! You successfully read this important alert message.', show: false }
    ];
  </code></pre>
  
  <p>In the alert tag I have added <code>ng-show="alert.show"</code>, but it seems it does not display any alert.
  You can find the code here: <a href="http://plnkr.co/edit/Qbv4A9u1SnQeJy9o81lK?p=preview" rel="nofollow">http://plnkr.co/edit/Qbv4A9u1SnQeJy9o81lK?p=preview</a>.</p>
  
  <p>What have I done wrong? Thanks in advance!</p>
