I am trying to initiate some jQuery (`$('#slider').leanSlider();`) after a successful Ajax response. Putting it in the success callback isn't working. I found an [answer here](https://stackoverflow.com/a/14220323/1536869) that I believe is related but I am having a difficult time understanding what I exactly have to do. How can I get that line to initiate after a successful Ajax response?

```
$('.post-link').click(function(e) {
    e.preventDefault();

    var post_id = $(this).attr('rel'),
        ajaxURL = site.ajaxurl;

    function projectShow() {
        $.ajax({
            type: 'POST',
            url: ajaxURL,
            data: {'action': 'load-content', post_id: post_id },
            success: function(response) {
                $('#project-container').html(response);
                $('#slider').leanSlider();    <--// This isn't initiating
                }
                return false;
            }
        });
    }
    projectShow();
});

```
