The process involves multiple steps -- activity on the server, followed by
Javascript updates in the UI. If the UI doesn't update as expected, there
is no reason to believe the problem must be with the code on the server --
the problem may be with the Javascript. I believe your code is updating
no error occured, i'm expected to update the quantity value through form
fields that user enter. nothing change, even after i refresh the page (F5),
the value in quantity form field and in span is not update. i'm not sure
what is running when i'm update the quantity form field and then press TAB
Rather than simply saying something didn't work, it helps if you can
explain in more detail exactly what you expected and what happened instead.
Did you get an error? How do you observe that it "didn't work"?

i'm trying to do it with session.order.get(id, 0)*0+qty is not work too. my

The .get() method retrieves values from a dict -- you cannot use it for
assignments.
