I just replaced my stock steering wheel on my 2011 Caliber Heat with a leather steering wheel off a 2009 Avenger with radio controls on it. The (2008-2010) Avenger and Caliber use the same steering wheel. Your Caliber will have the correct clockspring but you'll need to go the dealer and have them Starscan it to add sales code RDZ to your Calibers configuration in order to activate the radio control switch option. So far I've added this option to a 2011 Caliber Heat, 2008 Avenger SXT and a 2009 Challenger R/T.
See the instructions below.
