What is BrowseModel ? Why do you have two models at all?

You have to call the functions that trigger signals ListView will look for. For a clear of the data you have to do the beginresetmodel and endresetmodel. For the additem you have to use the begin/endinsertrows functions.

https://doc.qt.io/qt-5/qabstractitemmodel.html#protected-functions

Look for examples of how to build a model that shows how to do this. I think those are referenced in the model/view docs.
