ListView extension is not active if someone explicitly uses ViewItems attached properties or ListItem as delegate. As your sample doesn't use either of these, it cannot be the culprit. You don't seem to use anything from UITK so the only elements are instantiated at this time are the context properties. However neither of those should have any effect on the model setup.
