title: AngularJS: ngChecked not working
body: <p>I have the following radio button:</p>
  
  <pre><code>&lt;input type="radio" ng-value="option.text" ng-model="selected.value" name="option" ng-checked="poll_post.poll_option_id == option.id"&gt;
  </code></pre>
  
  <p>I have double checked <code>poll_post.poll_option_id</code> and <code>option.id</code> are equal. So the expression inside ng-checked is evaluated to true. But in the view, the option is not checked. What am I doing wrong? </p>
