Title: Notify parentView of childView changes for virtual views

Previously, if you had a standard view with a virtual child, we returned and
then cached the results of the virtual view's child views. However, if the
virtual view's child views change, the root level view is not notified of
this change and misreports the childViews. This commit corrects that issue.
