Mikrotik - Openflow

I’m trying to use Mikrotik as an openflow switch and I’m having trouble connecting to the SDN Controller, in case I’m using POX, in the tests I’m getting the connection between the controller and Mikrotik, but the flow table is not being updated , I am using 1 computer as controller and one connected to the openflow switch. Someone who understands openflow can help with the problem.
