title: Facebook FB.Event.subscribe does not work
body: <p>I'd like to follow how many likes I get on my page, but something is wrong. I am using the Facebook javascript event handler but it doesnt work. </p>
  
  <p>It should alerts me when I click on the like or on the dislike button but it does not do anything. Any idea where I am wrong? Thanks! And sorry for my english. </p>
  
  <p>Here is my UPDATED code:</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html xmlns:fb="http://ogp.me/ns/fb#"&gt;
  &lt;head&gt;
  &lt;title&gt;FBlike check&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &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 = "//connect.facebook.net/en_US/all.js#xfbml=1&amp;appId=00000000000000000";
    fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk')); 
  
  FB.Event.subscribe('edge.create',
      function(response) {
          alert('You liked the URL: ' + response);
      }
  );
  &lt;/script&gt;
  &lt;fb:like href="https://www.facebook.com/XYZ" send="false" layout="button_count" width="200" show_faces="false"&gt;&lt;/fb:like&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
