JSON for DataTables

i have searched but nothing that help me i have found. I have this JSON:

{
"id": 1,
"customer_ID": 1,
  "address": {
    "id": 1,
    "description": "primary address"
}
},{
    "id": 2,
    "customer_ID": 2,
    "address": {
        "id": 2,
        "description": "primary address"
    }
}

And if i try to add to my DataTables i have an error:

Requested unknown parameter 'id' for row 0, column 0

But, if i convert my JSON to this, the table is filled:

{"data": [
  {
    "id": 1,
    "customer_ID": 1,
    "address": 
    {
       "id": 1,
       "description": "primary address"
    }
  },{
        "id": 2,
        "customer_ID": 2,
        "address": 
        {
            "id": 2,
            "description": "primary address"
        }
    }]}

This is my Javascript code:

$("#tblCustomerAddress").DataTable({
                    data: result,
                    destroy: true,
                    columns: [
                        { "data": 'id' },
                        { "data": 'address.description' },
                        { "data": 'customer_ID' }
                    ]
                });

The "result" field is returned by my C# code:

public async Task<IActionResult> OnPostSaveAddressAsync(string GUID, string Address)        
{
    ...

    JsonResult Json = new JsonResult(wItem.Address_List);

    return Json;
}

My question is: how can i add this {data: []} to my JSON without manipulate with a stringbuilder? There are no default function that cover this?
