I actually wanted the selected the selected item.
But this cannot be done as the item is still not created yet, its just in
the setting its properties stage.
Anyways I had already assigned the data of the first selected item to my
right list(the other list).
All I wanted is the selected item in my left list ie the renderer should
change some state
that means I have to add state to the item renderer, that means lots of
changes :(
