Gitab CI : rules with changes to a dir/path

I'm trying to add this logic in my CI :

• don't add job to pipeline on merge_request_events or when merge request target branch is protected and when changes are made to any file in the e2e directory
• add job when the branch to which I'm merging to is one of the following dev, test or demo
• don't add job to pipeline in any other case.

Here are my rules

.ci-rules:
  rules:
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event" || $CI_MERGE_REQUEST_TARGET_BRANCH_PROTECTED == "true"'
      changes: 
        - "e2e/**/*"
      when: never
    - if: '$CI_COMMIT_REF_NAME == "dev" || $CI_COMMIT_REF_NAME == "test" || $CI_COMMIT_REF_NAME == "demo"'
      when: always
    - when: never


build:
  rules:
    - !reference [.ci-rules, rules]
  stage: build
  script:
    - echo "do something"
  allow_failure: false

Issue:
When I make changes to files in e2e directory only the job is still added to the pipeline.

I'd appreciate any help

I solved this with the following

.ci-rules:
  rules:
    - if: '$CI_COMMIT_REF_NAME == "dev" || $CI_COMMIT_REF_NAME == "test" || $CI_COMMIT_REF_NAME == "demo"'
      changes: 
        - "e2e/**/*"
      when: never
    - if: '$CI_COMMIT_REF_NAME == "dev" || $CI_COMMIT_REF_NAME == "test" || $CI_COMMIT_REF_NAME == "demo"'
      when: always
    - when: never
