sjg:grid in modal window not getting displayed atall

[fea jabi]

I am trying to use sjg:grid in a modal window which is opened from a tabbed 
panel.
 

Have the below code. Everything seams right to me. The modal window opens and 
displays other stuff but the grid is not getting displayed atall. The getJSON() 
in the action class is never getting called.
 

I did similar code in another page and it worked fine. Only difference being 
now I am trying it on the modal window.


 
Please need help with this. Not sure what am I missing here.
