If you use Chrome you can use developer tools Network tab to see if the AJAX request throws an error or not, makes it easier to debug AJAX requests that happen behind the scenes.

You need to use Ajax to post the id to the controller after getting it.

What did you Try? What did you Get? What did you Expect?
