Since you did not show any code, the only thing that I can think of is the you are using a javascript treeview that requires javascript.

Not enough information. A short but complete code sample (probably, not your existing code, but a sample) could help to help you. If you can do it, please use "Improve question" above.

Hi Sergey,

I have updated the Question with code that i am using. Could you please help me if you have any idea?

I see nothing which could prevent expand/collapse here, perhaps because this is incomplete sample. You could try to simplify code or create a separate sample without much processing to observe expanding/collapsing and add one step at a time to see where did you screw up it.
