clearing radio button selection

Guys, iam stuck in a situation where iam not able to clear the radio button selection in the SINGLESELECT tableview. I am using MVC approach and my layout is similar to bookshop example in SAP tutorial_4_mvc.

I found that even in the SAP example the raio button is not cleared when a new search is used. The radio button remains selected and it has to be clicked again to refresh and retrieve new values. But I would like to clear the selection.

Any help on how to clear previous radio button selection every time the page is reloaded?

Thanks.
