You might want to return super.trackwheelClick() instead.

Returning true means that the event is consumed. As you dont call the parent class handler, your list can't know it has been clicked, and it returns the last selected item (which is the first element by default).

As a final tip: don't use trackwheelClick, because it wont work in touchscreen enabled devices. Use navigationClick or FieldChangeListener instead.
