A better way of forcing data bound WPF ListBox to update?

I have a Listbox bound to an object property which is of type List<MyCustomType>() and I verified that the following code updates the listbox when the List is updated.

void On_MyObjProperty_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
   MyListBox.Items.Refresh();
}

If you’re still facing issues, scan the VS IDE output window (Ctrl+W, O) and see if you can spot any binding errors reported.
