Like Button for Tumblr Options

[fiveseven]

Saw a good example of this at http://cicerontheme.tumblr.com/. You can like a post from the homepage without having to go to the permalink page.

Here's what I've found from her source.

CODE

$(document).ready(function(){
    $('a.like_link').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).addClass('liked');
        return false;
    })
});

CODE

<a href="{Permalink}" class="like-link">Like</a>

I tried to recreate this button here: http://mockuptheme.tumblr.com

I click 'like' but it doesn't show up in my likes page.

What am I doing wrong?
