You'd require a Permanent Magnet motor to use the regen feature on that controller.

Most EV motors are Series Wound Motors, which to my understanding there is no way to have actual "regenerative" breaking from these motors, only forced motor breaking which takes up energy.
You forgot to mention shunt wound motors which can also do regen. Some people perfer to call them seperatly excited motors since the controller controls the shunt field and armature independently.

A 144 v controller is not that much, They run between $1250 and $ 1615 depending on the AMPS you have to remember when looking at that controller that is is being MARKED way up. I have a price list of the true prices if you are intrested
