I'm trying to construct a treetable dynamically by adding rows to the table.

The html part:

....

The js part:

$(".table tbody").append(""+jsonInput.value1+"")

while I see the data displayed to the table, I can't see the drop down arrow against the row. Upon inspecting the page of the example code, I see that a number of styles and classes added to the element that presents the drop down which are not added when I add the rows dynamically. How do I force the table to reapply the classes if I'm adding rows using jquery?
