Ruby on Rails

I have a product table and I try to run after_commit and after_rollback on create.

controller:

  product = Product.new form_params    if product.save      # code    else      # code    end

model:

  after_commit(on: :create) {      # code    }      after_rollback(on: :create) {      # code    }

after_commit works well but after_rollback wont work with on: :create param. When I remove the on: :create param, it triggers too but I need after_rollback to trigger just on create.
