Tumblr jQuery Like (grabbing from rel)

I coded a html5 (boilerplate) theme with masonry and infinite-scroll which so far has worked pretty well. Now I want to include reblog and like buttons on each post. I've tried to add this but for some reason the like button doesn't work.

URL to theme: http://inspiration.patrikarvidsson.com/

In the bottom of my script.js, I added this like-code.

$('a.like').click(function() {
     var post = $(this).closest('.post');
     var id = post.attr('id');
     var oath = post.attr('rel').slice(-8);
     var like = 'http://www.tumblr.com/like/'+oath+'?id='+id;
     $('#likeit').attr('src', like);
     $(this).toggleClass( 'liked' );
 });
 

Complete scripts.js can be found here:

And if needed, here's plugins.js: http://static.tumblr.com/e8lbmds/NDPm14qu6/plugins.js

The last line of the code above makes the link red; which I suppose indicates that the script responds. But no like is generated. Right after the initializing body tag, I have the following code:

<iframe id="likeit"></iframe>
 

Appertained css is the following:

#likeit { display: none; }
 .liked, .like:hover { color: red !important; }
 

Any ideas why it's not working?
