Issue is resolved . It was actually issue in RG settings. We should put the presentation as inline instead of none. But i still have another issue i gave on click activity on radio button to copy data when its selected. But on click on radio button it doesnot trigger. I tried with data transform also same issue.
Looks like radio button control is known to have issues when used with the grid. You might have to write a manual script to fulfill the requirement. Below is a script configured to refresh on click of a radio button. You can tweek it as per your requirement.
Alternately I would suggest using checkbox as the selection control.
