list: call "selected" callback after set focus to the selected item

in current code, when a list item is selected, "selected" callback is called first
and then focus is set to the item. this is a problem if another widget, popup for instance,
is created on top of the list in the callback function. in such a case, the popup should
get focused (not the list item). this patch fixes it by changing the order.
