If the linkBarEventHandler is a function inside the item renderer, I would
expect you to get a compile error, since the function would be defined in a
scope that the parent does not have access to, especially since when the
factory is defined, no instances of it exist.
If you want to have an event handler in the itemRenderer, attach the event
listener inside the item renderer, either in MXML or in AS.
The itemClick event of NavBar does not bubble, so the only place you can listen
for it is inside the itemRenderer. This is a separate and distinct event from
the ListBase itemClick, which will give you information about the entire object
that is represented in the DataGrid row. You could potentially catch the
NavBar itemClick in your renderer and create your own bubbling event that
describes what happened. You could also just listen for a mouse click anywhere
on the DataGrid and check the target property to see if the LinkBar is in some
way a parent of whatever was clicked.
