After commit events are not triggered on DynamoDB

Describe the bug
After commit events are not triggered on DynamoDB

To Reproduce
Steps to reproduce the behavior:
On a model with DynamoDB, set up aasm like this:

  aasm do
    state :sleeping, initial: true
    state :running, :completed, :error
    event :run, after_commit: %i[execute] do
      transitions from: :sleeping, to: :running
    end
   .....
  end

Call object.run!

The method returns true, but the state is not saved and the execute method is not called.

Expected behavior
The object state must be updated and the execute method should be called
