Hi,

I've got indeces name logstash-netflow-06, 07 etc (week number) and a template called netflow.

I used this script to add a field and surely the field shows up on the index pattern and when I do something like `GET logstash-netflow-06` is shows the new field as well. But when I do `GET _template/netflow` the new field does not show up.

Did I add a new field in the correct way? I would like the field to show up on the template as well.

```auto
PUT logstash-netflow-test-*/_mapping/netflow 
{
  "properties": {
          "application_id_trans": {
            "type": "text",
            "fields": {
              "keyword": {
                "type": "keyword",
                "ignore_above": 256
              }
            }
          }
     }
}
```
