jQuery ScrollFlow with wordpress

I try to add a ScrollFlow plugin from http://ift.tt/1P3j1cZ to my wordpress theme but I can not get it to work.

I've linked the plugin through wp_enqueue_script and added the classes scrollingflow and -opacity to the <article> tag but nothing happens with the element.

In the footer i added;

<script>    
(function($){

    new ScrollFlow();

    })(jQuery);
</script>

Does anyone know what I'm doing wrong?
