Make an ajax call and pass the page item to Application Process. This will ensure the Page item is submitted to server and value will be saved in the page item.
If you are Submitting the Page you can also use a Computation.
Just place it under Page Processing at After Submit.
This stores your Value my_value into Session State before Validation and Processing is starting.
Info: The Computation should have a Condition to run only on Button Click.
