ICINGA2 API Not making host modification - api

Question

i have problem with the API of ICINGA2.
i'm trying to add new variables with the POST call ,
i'm getting the required result,
But ICINGA2 didn't add the new var.
According to documentation:
http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/icinga2-api
With the following API, i creates all our hosts in vienna :
curl -k -s -u root:icinga -H 'Accept: application/json' -X PUT 'https://localhost:5665/v1/objects/hosts/server.example.com' \
-d '{ "templates": [ "generic-host" ], "attrs": { "zone": "Vienna", "address": "180.33.1.123", "check_command": "hostalive", "vars.os" : "Linux", "vars.agent" : "ssh" } }' \
| python -m json.tool
While this part works as expected,
The problem is once host created, i need to add various vars for different servers.
for example
Adding of the variable: "vars.servicename" : "DHCP_Servers"
If i'm going back to the documentation, the below API that will need to be execute:
curl -k -s -u root:icinga -H 'Accept: application/json' -X POST 'https://localhost:5665/v1/objects/hosts/server.example.com' \
-d '{ "templates": [ "generic-host" ], "attrs": { "zone": "Vienna", "address": "180.33.1.123", "check_command": "hostalive", "vars.os" : "Linux", "vars.agent" : "ssh", "vars.servicename" : "DHCP_Servers" } }' \
| python -m json.tool
When i ran the API , as expected i'm getting back:
{
"results": [
{
"code": 200.0,
"name": "server.example.com",
"status": "Attributes updated.",
"type": "Host"
}
]
}
But there is no changes that taking place on ICINGA/ host file.

Obviously the same user as in my inbox and the forums (https://monitoring-portal.org/index.php?thread/37160-adding-vars-with-api/&postID=234885#post234885) lately. Leaving this as a note here as it might help others to see why it does not work. That feature is just not implemented as it involves storing the applied changes, do a rollback, and re-apply. Not as simple as it sounds.
