Slider with submit button and updating value

I am looking for slider with a submit button but which nevertheless shows the current slider value, so a user can know what would be submitted. Perhaps somebody did this already ?
It would be for this notebook:

I added a few lines to Jeremy’s inputs bazaar to take advantage of the change event for range/submit forms:

It now updates the output display value while not triggering an input event. I am sure there is a more elegant solution than special casing this form but it is functional.
