Callbacks - how to get current control value?

Using Streamlit
2

ok , I figured it out myself. I more and more like the new session_state functionality!

import streamlit as st

st.title('the callback function always outputs the CURRENT string...')

def callback():

    st.text(st.session_state.mytext)

st.text_input('enter text',value='',on_change=callback,key='mytext')
