how do i update my listadapter data? the callback updates the ListProperty, but how do i use the ListProperty to update the adapter? maybe the ListProperty needs to a property of the adapter?

gistfile1.txt

here is the class:
class StudentDetailList(ListView):

    updater = ListProperty([])
    def __init__(self, **kwargs):
        super(StudentDetailList, self).__init__(**kwargs)

here are the adapters:

class carouselApp(App):
    global update

    def __init__(self, **kwargs):
        super(carouselApp, self).__init__(**kwargs)
        self.myAdapter= ListAdapter(data=getRow(0), args_converter=my_args_converter, selection_mode= 'multiple', allow_empty_selection= True,
                 cls=CompositeListItem)
        self.myAdapter124= ListAdapter(data=getRow(124), args_converter=my_args_converter, selection_mode= 'multiple', allow_empty_selection= True,
                 cls=CompositeListItem)
        self.myAdapter130= ListAdapter(data=getRow(130), args_converter=my_args_converter, selection_mode= 'multiple', allow_empty_selection= True,
             cls=CompositeListItem)
        self.myAdapter145= ListAdapter(data=getRow(145), args_converter=my_args_converter, selection_mode= 'multiple', allow_empty_selection= True,
             cls=CompositeListItem)
        self.myAdapter224= ListAdapter(data=getRow(224), args_converter=my_args_converter, selection_mode= 'multiple', allow_empty_selection= True,
             cls=CompositeListItem)
        self.myAdapter330= ListAdapter(data=getRow(330), args_converter=my_args_converter, selection_mode= 'multiple', allow_empty_selection= True,
             cls=CompositeListItem)
        self.SDA = studentDetailsAdapter(data=[], cls= ListItemLabel)
        self.SA= studentAdapter(data= StudentList(),allow_empty_selection= True, cls= ListItemButton )

this is the listview in kv:

  StudentDetailList:
                    id: details
                    adapter: app.SDA

and this is the callback:
def callback(instance):

    try:
        detailsList= StudentDetail(lastname(instance.text), firstname(instance.text))
        StudentDetailList.updater= (formatlist(detailsList))
        print 'SDA data is', StudentDetailList.updater
        StudentPhoto.source= photoName(detailsList[6])
        StudentPhoto.allow_stretch= True
        StudentPhoto.scale = 2
        return True
        #medicalinfo.text= detailsList[7]
        #emergencyContact.text= '[b]Emergency Contact: \n[/b]' + '[b]' + detailsList[3] + '[/b]'
    except (IndexError, AttributeError):
        StudentPhoto.source= '/home/clyde/kids/765-default-avatar.png'
