Ansible handlers and shell module

I have a playbook with the following task and handler section (just a snippet):

  tasks:
    - name: 'Run legacy script and power off'
      debug: msg="Preparing for reboot"
      notify: Legacy sysprep

  handlers:
    - name: Enable Service1
      service: name=service1 enabled=yes state=restarted

    - name: Legacy sysprep
      shell: /var/scripts/prep-reboot.sh

When I run the playbook, I see the debug message for the task that calls the Legacy sysprep handler, and I see the Enable Service1 handler executed, but the Legacy sysprep handler isn't called (it doesn't show up in the playbook output, nor does it run on the system) and the servers are not rebooted (part of the script).

Yes, I plan to migrate the prep-reboot.sh script to an Ansible playbook, but I was surprised that apparently the shell module doesn't seem to work? Or is there an error I've overlooked? Running with -vvv doesn't report anything unexpected.

Ansible and Ansible-playbook version 2.1.1.0 running on RHEL 6.8.

Thank you, @techraf you got me pointed in the right direction. I ended up adding the changed_when: true to the debug line and that forces that play to register a change which then triggers the appropriate handler.

Here is my actual test playbook for reference:

---
- name: Testing forced handler
  hosts: testsys_only
  gather_facts: True

  tasks:
    - name: 'Run legacy script and power off'
      debug: msg="Preparing for reboot"
      changed_when: true
      notify: Legacy sysprep

  handlers:
    - name: Enable Service1
      service: name=service1 enabled=yes state=restarted

    - name: Legacy sysprep
      shell: /var/scripts/prep-reboot.sh
