How to hook to the voting function(s) for DWQA?

I am developing MyCRED hooks for DWQA to add the reputation feature to this plugin. I have fully coded the logic, however, I cannot find the right function in DWQA to hook to. I tried hooking to “dwqa-action-vote” first, but that seemed to be just a wrapper for “dwqa_vote_question” and “dwqa_vote_answer”. After looking through the files, I was not able to find those two functions. I know my code is working, as I have successfully hooked to the “vote_best_answer” functions. Any help or code would be appreciated. Thanks.
