title: Facebook like button and add a comment event
body: <p>I've got like button on page and I'm catching events edge.create and edge.remove.
  I'm using this code from Facebook developers page:</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script&gt;
  (function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "http://connect.facebook.net/en_US/all.js#xfbml=1";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));
  
  
  window.fbAsyncInit = function() {
    FB.Event.subscribe("edge.create", function(targetUrl) {
      console.log("liked");
    });
  
    FB.Event.subscribe("edge.remove", function(targetUrl) {
      console.log("removed");
    });
  }
  &lt;/script&gt;
  
  &lt;div class="fb-like" data-href="https://developers.facebook.com/docs/plugins/" data-layout="standard" data-action="like" data-show-faces="true" data-share="false"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>But I can't find a way to catch events when user clicks <strong>"close"</strong> or <strong>"add a comment"</strong> button in popup.
  I tried with "comment.create" and "message.send" and it didn't work.</p>
  
  <p>Is there any way to catch these events?</p>
