When upgrading to the latest version (4.8) of the esri js api, I noticed that my popup template functions no longer are working. If you see the below JS Bin, the function app.populationChange doesn't work. If you switch back the cdn references to 4.7, the popup looks correct. I didn't see this breaking change in the release notes. It seems like a function within an object no longer works, but a standalone function still works. Is this a bug? Or is this intended behavior?
