Set text in TextInput

[хз кто]

How to make this code work? 

import kivy
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen

kivy.require('1.10.0')

Builder.load_string("""
<One>:
    BoxLayout:
        Button:
            text: 'button'
            on_press: root.button()

<Two>:
    ab: ab
    BoxLayout:
        TextInput:
            id: ab
"""

class One(Screen):
    def button(self):
        sm.current = 'two'
        Two().ab.text = 'test'  ''' <=== This does not work '''    

class Two(Screen):
    pass

sm = ScreenManager()
sm.add_widget(One(name='one'))
sm.add_widget(Two(name='two'))
sm.current = 'one'

class Main(App):
    def build(self):
        return sm

Main().run()

Try

    sm.current_screen.ids.ab.text = "Test"

You may need to add,

    class Two(Screen):
        ab = StringProperty('')

        #Two().ab.text = 'test'  '''<=== This doesn't work because you create new instance of class Two, which is not added to the sm widget'''
        sm.get_screen('two').ab.text = 'test'
