Titanium: How to close TabGroup within its Tab?

Question

How can I close the TabGroup within one of its tab ?

I want to close the tabGroup on a button click (Log out button) and want to display a window without the tab group. I know how to display a window but could find how to close tab group ?

I think, to hide tab group is not proper way. Also on another button (Login button) I am creating the tab group so...

Any suggestions ?

Thanks...
