I've raised a query with Qlik Support about this recently - the example provided in the cookbook and various other places works in SR10 but doesn't in SR7, I was specifically working with a gauge chart but it's the same functionality. I'm unsure if it "broke" for a few SRs but is now back - in any case, I opened your app and the pop-up function works fine in SR10, if you're able to upgrade to that SR?
I'll append your issue onto my query and let you know what I hear back.

I got a response from support earlier today, they confirmed this was a reoccurrence of a bug and lasted from SR7 to SR9. It's documented in the SR10 release notes as bug number 69025 (see below):
69025 [Text as Pop-up] in [Chart Properties] -> [Expressions] doesn't pop up custom message since QV11.2 SR7
