Because the browser's processing is asynchronous.
You could stick in a big wait (like you do earlier), and hope it's
enough, or check-wait-loop - but a better way is to trigger whatever
processing you want to happen on that value, from inside your
Value(String) method.
Better and more relevant than Firebog here would be to set a
breakpoint in your Value method.
