Hello Nisar,
did you make sure that your JavaScript patch gets executed? It's output has to
be connected to something that is necessary for rendering otherwise the patch
don't get executed and the inputs don't change. You also can check this by
selecting the Debug Mode in the Viewer window.
Is it possible for you to post your composition so we can have a look?
best,
