I think that the function setIndexWidget is requiring that deletion,
try to modify in this way the function addItem
(I'm not sure about what you want to do, so I can't suggest more):


    def addItem(self, item):
        self.data_model.appendRow(item)
        #proxy_index = self.proxy_model.mapFromSource(item.index())
        #self.setIndexWidget(proxy_index, item.item_widget)
