Does not work with #AJAX

Modifying a form with a hook we are able to use #AJAX for default date picker.

      $form['field_date_of_birth']['widget'][0]['value']['#ajax'] = [
        'callback' => 'people_form_alter_student_enable_legal_guardian',
        'event' => 'change',
        'progress' => [
          'type' => 'throbber',
          'message' => t('Verifying entry...'),
        ],
      ];

This will trigger the AJAX request and allow updating the form.

However, with the new type bootstrap_date_time AJAX is never triggered on change.
