Elastic Beanstalk ebextension config not running for instances created by autoscaling group thus not running cloudwatch cmds

Question

Elastic beanstalk will run my ebextension config when I do a fresh deploy of the application but when I terminate one of the instance an auto scaling group will trigger and launch an instance to satisfy the min no. of instances to run.

When the instance is launched using the ASG it is not running the ebextensions config file

here is my ebextension cloudwatch.config file

 files:
  "/opt/aws/amazon-cloudwatch-agent/bin/config.json":
    mode: "000600"
    owner: root
    group: root
    content: |
      {
        "agent": {
          "metrics_collection_interval": 300,
          "run_as_user": "root"
        },
        "metrics": {
          "namespace": "Devops/Ec2/System",
          "append_dimensions": {
            "AutoScalingGroupName": "${aws:AutoScalingGroupName}",
            "InstanceId": "${aws:InstanceId}",
            "InstanceName": "${aws:InstanceName}"
          },
          "metrics_collected": {
            "disk": {
              "measurement": [
                "used_percent"
              ],
              "resources": [ "/" ]
            }
          }
        }
      }

when i connect to instance i should see something like this

cd /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.d/
[amazon-cloudwatch-agent.d]# ls
file_beanstalk.json  file_config.json

but this is what I am seeing

cd /opt/aws/amazon-cloudwatch-agent/etc/amazon-cloudwatch-agent.d/
[amazon-cloudwatch-agent.d]# ls
default
