Is not working in ansible 2.9.10

[elsebasan]

• name: Change ownership of the installation directory if it had to be created
  file:
  path: "{{ dynatrace_wsagent_linux_install_dir }}"
  owner: "{{ dynatrace_wsagent_owner }}"
  group: "{{ dynatrace_wsagent_group }}"
  when: dynatrace_wsagent_create_install_dir_result | changed
  become: yes
  The syntax
  when: dynatrace_wsagent_create_install_dir_result | changed
  FAILED! => {"msg": "The conditional check 'dynatrace_wsagent_create_install_dir_result | changed' failed. The error was: template error while templating string: no filter named 'changed'. String: {% if dynatrace_wsagent_create_install_dir_result | changed %} True {% else %} False {% endif %}

If I use
when: dynatrace_wsagent_create_install_dir_result is changed
This work.
