Pass variable value to a job in a template from previous job

Hello,

This is my yaml  pipeline

stages:
- stage: 'build'
  displayName: 'Build'
  jobs:
  - job: 
    steps:
    - task: CmdLine@2
      name: 'calculateAppVersion'
      displayName: 'Calculate Chart  Versions'
      inputs:
        script: |
          chartVersion="abcd1234"          
          echo "##vso[task.setvariable variable=chartVersion;isOutput=true]$chartVersion"   
  - template: ./template-scan.yaml
    

This is my template-scan

jobs:
- job: 'scan'
  variables: 
    containerTag: $[ dependencies.${{parameters.dependentJob}}.outputs['setVariable.chartVersion'] ]
  steps:  
   .
   .
   .

I am unable to access the container Tag value. Its always blank in template. Does this approach of dynamically creating the variable and then reading it in another job within template works.. If not, can anyone suggest some solution.

Thank you.

Kind Regards,

Tanul
