Facebook Like button click event on welcome page should open popup window of page tab

Question

I want to capture Like button click event in facebook page in my facebook.

If anyone click on like button, it should open a popup window of page tab http://www.facebook.com/wineselectors?sk=app_190348341034091

I have used to below code to capture like click, but it is not working.

<html> <script type="text/javascript"> 
 FB.Event.subscribe('edge.create', function(response) {
          alert('the user likes a page');
    });

</script> <body> <center> <img src="http://www.wineselectors.com.au/images/UserUploadedImages/facebook-like--image.jpg" /> </center> </body> </html>

I am trying to develop an aspx page for welcome tab but how can I get signed_request in my aspx page and how to decode the signed_request. I have read some of the articles they were using Jason but i could not able to use Jason in my system.

When someone likes your page, the page gets completely refreshed and you would need to decode and inspect the signed_request HTTP POST parameter in server code (not javascript) to see if they like your page. Then from there you could redirect the user as necessary.
