title: FaceBook like-button callbacks not working
body: <p>Can anyone tell me why callbacks are not working for the like-button code given below? The code is a standard set up in JavaScript as far as I can see. The first button is initialized, then the API is loaded asynchronously, and callback functions are provided.</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;script&gt;
  
  window.fbAsyncInit=function(){
      FB.init({
          appId:'',//App ID
          status:false,// check login status
          cookie:true,// enable cookies to allow the server to access the session
          xfbml:true// parse XFBML
      });
      // Additional initialization code here
  
      FB.Event.subscribe('edge.create', function(response) {
          //alert("user_id1:&lt;?php echo $user_id1; ?&gt;, user_id2:&lt;?php echo $user_id2; ?&gt;");
          /*var data={
              action:"ap_buttons_give_points",
              author_id:&lt;?php echo $author_id; ?&gt;,
              post_id:&lt;?php echo $post_id; ?&gt;,
              type:"like"
          }
  
          jQuery.post("&lt;?php echo $ajax_url; ?&gt;",data,function(resp){
  
          });*/
      alert('You just liked the page!');
  });
  
      FB.Event.subscribe('edge.remove', function(response) {
          /*var data={
              action:"ap_buttons_take_points",
              author_id:&lt;?php echo $author_id; ?&gt;,
              post_id:&lt;?php echo $post_id; ?&gt;,
              type:"like"
          }
  
          jQuery.post("&lt;?php echo $ajax_url; ?&gt;",data,function(resp){
              //alert("fb remove:"+resp);
          });*/
      alert('You just unliked the page!');
  });
  };
  
  // Load the SDK Asynchronously
  (function(d){
      var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
      if (d.getElementById(id)) {return;}
      js = d.createElement('script'); js.id = id; js.async = true;
      js.src = "//connect.facebook.net/en_US/all.js";
      ref.parentNode.insertBefore(js, ref);
  }(document));
  &lt;/script&gt;
