Perform Cron job in ansible playbook on ec2-user

Hello Team,

I am working on the cron jobs in Ansible. I want to perform cron jobs operations on AWS ec2 instance. I got success status on ec2 instance in the control machine while i have ran the playbook. But within the instance, when i tries the "crontab -l" command, it gave

“No cron jobs available for ec2-user”
I want the git modifications in the ec2 iinstance. So please help me out.
This is my playbook part. Please help me to activate my task on ec2 instance.

Thank you.
