Loop through a jQuery .post function multiple times

So I am using the jsplayer HTML5 player on my wordpress site, as well as some custom script to load in the next post and replace the old content once the video is finished:

    $(document).ready(function(){
        $(".video-js").bind('ended', function(){
            var sStr = "<?php echo get_permalink(get_adjacent_post(true,'',true)); ?>";
            var adj_numb = "<?php 
                            $adj = get_adjacent_post(true,'',true); 
                            $numb = $adj->ID;
                            echo $numb
                            ?>";
            var cur_numb = "<?php echo $post->ID; ?>";
            $.post(sStr, function(data) {
                var content = $( data ).find( '#post-' + adj_numb);
                $( "#post-" + cur_numb ).html( content );
                var vid = VideoJS.setup( "vid" );
                vid.play();
            });
        });
    });

This works great, for exactly one video. It loads in the next video and plays it, but after the 2nd video plays it just stops. I figure this means I have to sort of “reset” all my variables and start again from the beginning of the script, and that it’s not doing this because of $(document).ready(function(), as it’s already all loaded at this point.

Is there a standard way to loop through this script again, and re-set all the variables after its run once?

Thanks!

EDIT: Rendered JS:

    $(document).ready(function(){
        $(".video-js").live('ended', function(){
            var sStr = "http://www.theloniousfilms.com/zachmath/volkswagon/";
            var adj_numb = "94";
            var cur_numb = "96";
            $.post(sStr, function(data) {
                var content = $( data ).find( '#post-' + adj_numb);
                $( "#post-" + cur_numb ).html( content );
                var vid = VideoJS.setup( "vid" );
                vid.play();
            });
        });
    });
