DropDownTree's refresh method does not re-render the nodes

[IvanDanchev]

Bug report

The DropDownTree's refresh API method re-renders only the noDataTemplate and the footerTemplate. The nodes are not re-rendered.

Reproduction of the problem

Current behavior

Only the noDataTemplate and the footerTemplate are re-rendered.

Expected/desired behavior

The method should also re-render the nodes, similarly to the DropDownList's refresh method, which re-renders its items.

Environment
