Yeah it works now.
As for the project, honestly I can't tell what's going wrong.
My suggestion would be to just make use of hierarchies though, see construct.net/en/make-games/manuals/construct-3/interface/layout-view That should cut down on some of the complexities you have going on.
If you have your button and add the text object as a child (or as many other objects as you wish) all you need to do is tween the button, and all the children will scale accordingly. This also circumvents the issue that tweening the text object scale doesn't scale the font size.
