Adding new rows on a draggable table via jquery

I have a draggable table with preloaded “new items” – sorta like the Power Edit feature of the menu_editor module. Everything works perfect.

However, I want to have a button that adds a new row via jquery. I was able to do this via the following code. However, the new rows added by jquery are not draggable. What can i do to make it work? Is it even possible?

var preloaded_items_count = '.$preloaded_items_count.'; $("#edit-add-new-item").click(function(){   var append_tr = $("#guide-pages-table tr:last").clone();   var replace_pattern = new RegExp("new-" + preloaded_items_count, "g");   var new_item_id = "new-" + (preloaded_items_count + 1);    //append_tr.find("a.tabledrag-handle").remove();   append_tr.html(append_tr.html().replace(replace_pattern,new_item_id));   preloaded_items_count = preloaded_items_count + 1;    //Drupal.tableDrag.prototype.makeDraggable(append_tr);   $("#guide-pages-table > tbody:last").append(append_tr);   return false; });
