Missing notification on Messaging icon?

[AC Question]

I recently upgraded to a Moto G phone, and one thing is really driving me nuts. On my old phone (Samsung Galaxy Ace II), when I got a new text or email, I would have a notification in the status bar AS WELL AS a little red number on the corner of the icon itself.

This red icon seems to be missing on the Moto G (I still get an icon in the status bar, and the LED light) and for the life of me I can't figure out how to turn that notification on.
