title: No callback with FB.ui
body: <p>I can't get the Facebook UI callback to run.  I've used the example from the FB dev site:</p>
  
  <p><a href="https://developers.facebook.com/docs/reference/dialogs/feed/" rel="nofollow">https://developers.facebook.com/docs/reference/dialogs/feed/</a></p>
  
  <pre><code>FB.init({appId: "YOUR_APP_ID", status: true, cookie: true});
  
  function postToFeed() {
  
      // calling the API ...
      var obj = {
        method: 'feed',
        redirect_uri: 'YOUR URL HERE',
        link: 'https://developers.facebook.com/docs/reference/dialogs/',
        picture: 'http://fbrell.com/f8.jpg',
        name: 'Facebook Dialogs',
        caption: 'Reference Documentation',
        description: 'Using Dialogs to interact with users.'
      };
  
      function callback(response) {
        document.getElementById('msg').innerHTML = "Post ID: " + response['post_id'];
      }
  
      FB.ui(obj, callback);
  }
  </code></pre>
  
  <p>When I run it on my site I get no callback
