title: jQuery Sortable Newly appended elements not recognized
body: <p>How does jQuery UI sortable method <a href="http://jqueryui.com/demos/sortable/#method-refresh" rel="nofollow">refresh</a> works. I have Multiple <code>span</code> tag with <code>P</code> tags inside. The <code>P</code> tags are sortable from one <code>span</code> to another. However when i add a new span with p tags inside, the new P tags are not recognized. The refresh method is supposed to make newly added recognizable. but it doesn't seem to be working or doing anything.  <code>$('span').sortable('refresh')</code>.</p>
