Elastic Stack Elasticsearch

I am using ES 5.5.
Here is what I am stuck at.
I am able to add new nested array element.
But I also need to update any existing ones.
my mapping

{
	"email_misc": {
		"mappings": {
			"emails": {
				"properties": {
					"email": {
						"type": "text"
					},
					"email_data": {
						"type": "nested",
						"properties": {
							"created_time": {
								"type": "long"
							},
							"direct_email": {
								"type": "integer"
							},
							"email_id": {
								"type": "long"
							},
							"email_identifier": {
								"type": "text"
							},
							"email_priority": {
								"type": "integer"
							},
							"email_sent": {
								"type": "integer"
							},
							"email_subject": {
								"type": "text"
							},
							"mg_key": {
								"type": "text"
							},
							"recipient_email": {
								"type": "keyword"
							},
							"recipient_name": {
								"type": "text"
							},
							"status_bounced": {
								"type": "integer"
							},
							"status_clicked": {
								"type": "integer"
							},
							"status_complained": {
								"type": "integer"
							},
							"status_delivered": {
								"type": "integer"
							},
							"status_dropped": {
								"type": "integer"
							},
							"status_opened": {
								"type": "integer"
							},
							"status_unsubscribed": {
								"type": "integer"
							}
						}
					},
					"email_key": {
						"type": "keyword"
					},
					"recipient_name": {
						"type": "text",
						"fields": {
							"keyword": {
								"type": "keyword",
								"ignore_above": 256
							}
						}
					}
				}
			}
		}
	}
}

I have a record like
Selection_006

i want to update the status a nested record
Selection_007
I tried

{
  "script": "for (int i = 0; i < ctx._source.email_data.size();i++){if(ctx._source.email_data[i].email_id == params.id){ctx._source.email_data.remove(i);i--;}}",
  "params": {
    "id": 165
  }
}

gave me
Selection_008

but not data is removed.
I also tried

{
  "script": "for (int i = 0; i < ctx._source.email_data.size(); i++){if(ctx._source.email_data[i].email_id == params.remove_id){ctx._source.email_data[i].email_subject = 'Updated John';}}",
  "params": {
    "id": 165
  }
}

ALSO gave me success but nothing was updated.

what is the correct way to do it.

thank you
