PyQT list view does not respond to data signal

Question

I am following some tutorials and trying to customize the list model. In my main window, there are two kinds of list that access the same model. When I update an item in one list, the other list is not updated until it receives focus (I click on it). Thus, it seems that the dataChanged signal is not emitted, but I cannot understand how my code is different from any of the examples that I am based on.

main.py

class Main(QtWidgets.QMainWindow):
    def __init__(self, parent=None):
        super(Main, self).__init__(parent)
        self.ui = uic.loadUi("mainwindow.ui", self)

        # Test model and listviews
        data = [10,20,30,40,50]
        myModel = model.MyListModel(data)
        self.ui.listView.setModel(myModel)
        self.ui.listView_2.setModel(myModel)

model.py

class MyListModel(QtCore.QAbstractListModel):
    def __init__(self, data=[], parent=None):
        super(MyListModel, self).__init__(parent)
        self.__data = data

    def rowCount(self, parent=QtCore.QModelIndex()):
        return len(self.__data)

    def data(self, index, role=QtCore.Qt.DisplayRole):
        row = index.row()
        if role in (QtCore.Qt.DisplayRole, QtCore.Qt.EditRole):
            return str(self.__data[row])

        if role == QtCore.Qt.ToolTipRole:
            return 'Item at {0}'.format(row)

    def flags(self, index):
        return QtCore.Qt.ItemIsEditable | QtCore.Qt.ItemIsEnabled | QtCore.Qt.ItemIsSelectable

    def setData(self, index, value, role=QtCore.Qt.EditRole):
        if role == QtCore.Qt.EditRole:
            self.__data[index.row()] = value
            self.dataChanged.emit(index, index)
            return True
        return False

Can anyone see what is wrong here? FYI I am using PyQT5.2.1 and Python 3.3.

Answer 1

dataChanged. Qt4 :

    dataChanged(const QModelIndex & topLeft, const QModelIndex & bottomRight)

Qt5 :

    dataChanged(const QModelIndex & topLeft, const QModelIndex & bottomRight,
                const QVector<int> & roles = QVector<int>())

PyQt-5.1.1, . , , . , .

, dataChanged, PyQt5:

    self.dataChanged.emit(index, index, [])

, , , :

    self.dataChanged.emit(index, index, [QtCore.Qt.EditRole])

Answer 2

:

self.dataChanged.emit(index, index, ())

(python 2.7, PyQt5).
:

self.dataChanged.emit(index, index, [])

self.dataChanged.emit(index, index, list())
