MVC Single Model Two Dialogs - with PyQt

MVC Single Model Two Dialogs - with PyQt

Hi, i am trying to use a single dataModel for two different forms in hopes that when the dataModel is changed in one form it will effect the other as well. but that doesnt work.

i built two forms:

Form_1: has two views set to a model class.
Form_2: has one view connected to the same model class.

if i change data on any view on Form_1 it changes it both view's however Form_2 doesn't change?
does any body have any suggestions of how to make to saparate forms which are connected to the same model, update when data is changed in one.

here is my code:

CODE --> python

class Model(QStringListModel):
    def __init__(self, parent=None):
        super(Model, self).__init__(parent)
        data = QStringList()
        data << "one" << "two" << "three" << "four" << "five"

class Form_2(QDialog):
    def __init__(self, parent=None):
        super(Form_2, self).__init__(parent)
        self.model = Model()
        self.combo = QListView()
        layout = QVBoxLayout()

class Form_1(QDialog):
    def __init__(self, parent=None):
        super(Form_1, self).__init__(parent)
        self.model = Model()
        self.listView = QListView()
        self.combo = QComboBox()
        self.form2_button = QPushButton("Open Form_2")
        layout = QVBoxLayout()
        self.connect(self.form2_button, SIGNAL("clicked()"), self.form_2)
    def form_2(self):
        self.ft = Form_2()

app = QApplication(sys.argv)
form = Form_1()

any help would be immensely appreciated.
