我正在嘗試使用SDK Facebook來檢測likebox上的按鈕「like」並調用一個函數，但它不起作用。這裏是我的代碼：關於點擊按鈕的Facebook Likebox事件

     channelURL : 'xxxx/facebook/channel.html', // Channel File 
     status  : true, // check login status

    // Additional initialization code here 
    }; 

    // Load the SDK Asynchronously 
    (function(d){ 
    var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;} 
    js = d.createElement('script'); js.id = id; js.async = true; 
    js.src = "//connect.facebook.net/en_US/all.js"; 
    d.getElementsByTagName('head')[0].appendChild(js); 
    }(document)); 
</script> 
<script type="text/javascript"> 
FB.Event.subscribe('edge.create', 
    function(response) { 
     alert('You liked the URL: ' + response); 
    } 
); 
</script> 

<fb:like-box href="http://www.facebook.com/MarwenClubiiste" width="292" show_faces="false" stream="false" header="false"></fb:like-box> 

</html>
