python - How to change the value of the widget argument in KivyMD

Question

How do I change the widget argument at the click of a button? That is for example there is a button

MDRaisedButton:
        id: but
        pos: (150,150)
        text: 'Старый текст'
        on_press: app.func()

How can I replace the text argument with, for example, 'New text' by clicking the same button? What do I need to write in the func function to make it work?

def func(self, instance_button):
    instance_button.text = "New text"
