[1.8] Cannot change ExtendedPlayer fields.

[FlamingVikingGoat]

I'm trying to add mana values for players, but I can't seem to change them. I have an item that should change the max value for mana when I right click it, but it doesn't seem to work; I have println's for debugging and they keep displaying that my max mana is 0.
