Adding cuts in integer callback

I'm solving an MILP problem, trying to use the one tree benders decomposition approach, I can manage to go and solve dual problem with the information of incumbent solution but I am not sure if the new cuts are added to the main problem  after solving the dual problem. 

 

Also is it possible to add new cuts in integer solution cut backs and solver will resolve the model with the new additional cuts? I have tried to use sethidden(constraint, false) function and setmodcut seperately in callback but I am not sure it worked like that.

 

Many thanks in advance.
