Kivy - editing label when button clicked

I wish button1 to edit Label 'etykietka' when clicked, but i don't know how. Have you got some ideas?

class Zastepstwa (App):

def build(self):
    lista=WebOps().getList()
    layout = BoxLayout(orientation='vertical')
    etykietka = Label(text='aa', font_size=10)
    button1 = Button(text='aa')
    button1.bind(callback)
    layout.add_widget(etykietka)
    layout.add_widget(button)
    return layout

def callback (instance):
    newLabelText='kkk'
    #?

Also, make sure you have the callback function indented and directly after the build function. Otherwise the callback function won be recognized in the bind statement.

you need to pass your label to callback, a nice way to do it is to use the partial function

from functools import partial

change callback signature for

def callback(label, instance, *args):
    label.text='kkk'

then bind the callback like this

button1.bind(on_press=partial(callback, etykieta))

that should do it.
