I think the answer has already been hit upon here: the Kanima was bound to a master (first Matt, then Gerard). While that was the case, an Alpha's roar wouldn't be able to force it to change. Remember that Jackson could never change voluntarily anyway. He was controlled by the Kanima's impulses, and it in turn was controlled by it's master.
