Using this code I can track if someone follow my account

  1.     <script type="text/javascript" src="http://platform.twitter.com/widgets.js"></script>
  2.     <script type="text/javascript">
  3.         function debugEvent(intent_event) {
  4.             console.log(intent_event);
  5.             alert(intent_event);
  6.         }
  7.         twttr.events.bind('follow', debugEvent);
  8.     </script>

but if I have more than one Twitter accounts , for an example

My website has two twitter links

  1. https://twitter.com/facebook
  2. https://twitter.com/twitter

How could I track which one is clicked to follow
