What file - Timeline change?

I need the following javascript code to run every single time the wall-timeline content changes, and it needs to run after the changes have been made not before.

var myTextEl = document.getElementById( 'bxwall' );
myTextEl.innerHTML = Autolinker.link( myTextEl.innerHTML );

I have tried looking in the modules/boonex/wall/js/ view.js and post.js but can't figure out which function (if either of these are the right file) to add the script to. 

Any suggestions?
