How to pass values to MVC controller from JSTree Menu

Question

Hi,
I am using the example in -

http://codemyne.net/articles/Populating-Treeview-with-checkboxes-using-MVC3Razor-Jstree-Jquery.aspx?visitid=149&type=2

I want to pass values of the selected node to the controller. The author of the article is displaying the values in a message box; I want to show the selected item's text or id it in a TextBox  in the same page or pass it to the controller. Can anyone help me to do it?

Thanks,
