the function MedicalLst() works If i use it to build student_list.

furthermore, the callback prints the correct list to the terminal.

the question is why won't the callback update the listview?

here is the binding: btn1.bind(on_release= (callback2))

here is the callback:

def callback2(instance):
    global student_details
    try:
        if instance.state ==  'down':
            student_list.adapter.data = MedicalList()
        elif instance.state ==  'normal':
            student_list.adapter.data = StudentList()
        student_list.adapter.cached_views = []
        student_list.populate()
