Update Custom Field Type Field by REST API SharePoint 2013

Question

I have a REST api to update the different fields of Item in the list

$.ajax({ url: projectSiteURL + "/_api/web/lists/GetByTitle('MyList')/items(10)", xhrFields: { withCredentials: true }, crossDomain: true, type: "POST", data: JSON.stringify ({ '__metadata': { 'type': 'SP.Data.MyListListItem' }, 'DocDescription': "test", 'CustomStatus': "Specific value here in custom field type format" }), headers: { "Accept": "application/json;odata=verbose", "Content-Type": "application/json;odata=verbose", "X-RequestDigest": $("#__REQUESTDIGEST").val(), "IF-MATCH": "*" , "X-Http-Method": "MERGE" }, success: function(data, status, xhr) { console.log(status); }, error: function(xhr, status, error) { console.log(error); } }); 

When I execute above code, it gives me error:

"The property 'CustomStatus' does not exist on type 'SP.Data.MyListListItem'. Make sure to only use property names that are defined by the type."

I have that field on the list of type custom field type which I created by code from here.

I have also checked when I get item with REST Api, even when I do have value in that field, I don't get that field value in a result. Can someone tell me please what am I missing here.

So far found nothing for the answer.

Seems it is not possible with the REST API.

But if someone can correct me here, please add answer.
