How the tag is pushed to repo?

I am working on a pipeline that includes two stages:

Stage 1: run build, if successful, generate a new tag. This works, I can see a new tag generated after commit code to master branch.

Stage 2: trigger a deployment only when a new tag generated. This doesn't work with below pipeline

name: CICD on version deploy

on:
  push:
    tags:
      - 'v[0-9]+.[0-9]+.[0-9]+'

jobs:
  deploy:
    name: deploy-prod
    runs-on: ubuntu-latest
    # if: github.ref == 'refs/heads/master'
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: run production deploy
        run: |
          echo "run production deploy"

But when I manually create and push a new tag, above pipeline will be triggered automatically (see here ) . Any hints for me?

reference:

pipeline for master branch: master.yml pipeline for tag/version generated: verison.yml
