[PySide] DataMapper issues

[Adrian Klaver]

OpenSuse 12.2
pyside 1.1.2-1.11
Python 2.7.3

I have the following and it will not save the data to the database:

class PlantForm(QtGui.QMainWindow):
     def __init__(self, parent=None):
         super(PlantForm, self).__init__(parent)
         loader = QtUiTools.QUiLoader()
         self.ui = 
loader.load("/home/aklaver/software_projects/greenhouse_app/python_code/plant_app_qt/forms/plant_form.ui")
         self.model = QtSql.QSqlTableModel(self, db=db)
         self.model.setTable("plant1")
         self.model.setSort(0, QtCore.Qt.AscendingOrder)
         self.model.setEditStrategy(self.model.OnManualSubmit)
         self.model.select()
         self.dm = QtGui.QDataWidgetMapper(self)
         self.dm.setSubmitPolicy(self.dm.ManualSubmit)
         self.dm.setModel(self.model)
         self.dm.addMapping(self.ui.plantNoLi, 0)
         self.dm.addMapping(self.ui.commonLi, 1)
         self.dm.addMapping(self.ui.genusLi, 2)
         self.dm.addMapping(self.ui.speciesLi, 3)
         self.dm.toFirst()
         self.saveBtn = self.ui.saveBtn
         self.saveBtn.clicked.connect(self.model.submitAll)
         self.ui.show()
         self.center()

     def center(self):
         qr = self.frameGeometry()
         cp = QtGui.QDesktopWidget().availableGeometry().center()
         qr.moveCenter(cp)
         self.move(qr.topLeft())

I am obviously missing something, I am just not sure what?
I tried the above with OnFieldChange for the model and AutoSubmit for 
the DataMapper. When I opened the form the first field would update to 
its existing value bit then I could not change anything. The changed 
value stick in the widget, they just do not get to the database.

Thanks,
