PyQT5: get filename on button click, getting an attributeError

Question

I'm trying to get all my filenames after I click on a button. I am getting the following error after I run app.py -

<lib.create_form_elements.CreateFormElements object at 0x000002286E0B9948> Traceback (most recent call last): File "\controller\addNewItemController.py", line 12, in update_filename self._model.fname = value File "\models\addNewItemModel.py", line 14, in fname self._flname.emit(value) AttributeError: 'bool' object has no attribute 'emit'.

what am I doing wrong?

app.py

        self.main_view = AddNewItem(self.model, self.main_controller)
        self.main_view.show()

    app = App(sys.argv)
    sys.exit(app.exec_())
