Hi Abhijeet,
From above I can understand, is that you want to show some details of the linked which clicked.
One suggestion I can give in your case is that instead of replacing the current List UIBB with the detailed form UIBB(which is bit difficult) try to open a dialog box(pop up) in which you can place your form UIBB contents.
This can save lot of time of yours. 
Regards,
Sanket.
