You're replacing the filter, but the (old) filter is already held (passed
into) in your property models. You have two options:
1 - Add a reset() method to your PersonFilter and call that instead of
replacing it with a new one.
2 - Make your filter variable an IModel<PersonFilter> that holds the actual
filter object. Then pass this model into your property models (where you're
currently passing in the actual filter object). Then call
filter.setObject(new PersonFilter())
