Accesing dynamic Treeview nodes Please help me

Question

can any one explain to me why this mouse up module is not working as I expected. there is some thing is wrong here I am unable to find. It is working only for 1 iteration then it is not showing any dailog box. Though while dubugging the code the curser going through the corresponding switch statement but I don't why it's not displaying even context menu.

Why so?  How come dubugging is different to that of actual o/p


Please help me
thanks
