title: FB ui feed get message after posting on wall
body: <p>I'm using this function to initiate a UI feed to post on my wall a content from my website. : </p>
  
  <pre><code> FB.ui({
        method: 'feed',
        name: myname,
        link: window.location.href,
        picture: mypic,
        caption: '',
        description: desc
      },function(response){}
    });
  </code></pre>
  
  <p>I need to execute a callback inside the callback in which I can retrieve the message that the I inserted in the Facebook Dialog, I'm searching but not finding a way to get it, I also tried to delegate a keydown event to the dialog's textarea , but It does not work.</p>
  
  <p>How can I solve this?</p>
