I'm trying to find a way to run a javascript function when someone leaves a comment on something in my facebook app via the comment pluggin. Is there any way I detect the event. Would also like to a the same when some clicks the "Like" button.

Any Ideas?

Here is how : http://developers.facebook.com/docs/reference/javascript/FB.Event.subscribe/

You can use the FB.Event.subscribe function. http://developers.facebook.com/docs/reference/javascript/FB.Event.subscribe/

FB.Event.subscribe('comments.add', function (response) {
    // do something with response
});

I haven't tried this out myself, but I've read you should add the notify="true" attribute to the fb:comments tag for it to work.
