title: Render partial with coffeescript
body: <p>I'm trying to trigger a partial reload in the drag &amp; drop UI when an element is released. The following code resides in my <code>projects.js.coffee</code> file. I'm not sure how to dynamically trigger reordering (last row). Thanks.</p>
  
  <pre><code>jQuery -&gt;
    $('#requirements-list').sortable
      axis: 'y'
      update: -&gt;
        $.post($(this).data('update-url'), $(this).sortable('serialize'))
        $("#requirements-list").html('&lt;%= j(render("projects/requirements")) %&gt;');
  </code></pre>
