Thanks for the reply,
You're 100% right, I had thought that every time I changed page another
callback was being added and my function comparison was failing which is
why I switched to toString().
What actually was happening is I had several instances of the controller on
different pages and each different controller declaration was being treated
as a separate callback, which is the desired behaviour but looked like a
bug when I thought the controller only had a single instance
