Dynamically Created Tree Panel and item click event not firing.
I have created a view port layout and designed a panel to load the tree panel menu layout. I was able to generate the layout without any issue but i am having trouble ItemClick list of the Tree Panel. It's doesn't seem to be firing at all. Below is my code.
The Javascript method i am trying to call is 'loadContentPage'.
Default.aspx
