I have seen the presentation and there is a functionality that can be
used to update views after a function call, or even an asynchronous
function call. One concept often used is this tag:

I use it a lot too when needing to update a view automatically after
some data has been updated.
Perhaps something like that can be incorporated within Guasax? Either
way, this bit of code has been very helpful for me.
