If nerves don't regenerate (or do so very slowly), how do transplanted organs work?

Say someone receives a liver transplant, do the surgeons reconnect the nerves? If so, a) how and b) is the liver capable of functioning without autonomic nervous input until the nerves heal? If that is the case, how is possible for an organ to survive without any nervous input? Also say a different someone receives a stomach transplant (uncommon probably), would they still experience stomach discomfort or satiety?

A liver will function without being hooked up to the nervous system. Most organs that are transplanted will. The heart for instance can regulate it's ritme on it's own. In a normal situation the heart is hooked up to the sympatic (autonomic) nerves system but after a transplant it will do it's job fine without this connection. 

There is however some evidence for the limited regrowth of these sympatic nerves after transplant in some patients:
