Gorilla jsonrpc getting empty response

Why does my jsonrpc method return an empty response?

type Args struct {
  A, B int
}

type Response struct {
  sum int
  message string
}

type Arith int

func (t *Arith) Add(r *http.Request, args *Args, reply *Response) error {
  reply.sum = args.A + args.B
  reply.message = "Do math"

  // this does not work either

  //*reply = Response{
  //  sum : 12,
  //  message : "Do math",
  //}

  return nil
}

Request:

{"method":"Arith.Add","params":[{"A": 10, "B":2}], "id": 1}

Response:

{
  "result": {},
  "error": null,
  "id": 1
}

However, if I set the type of reply to *string, then this will work fine:

*reply = "Responding with strings works"

Response:

{
  "result": "Responding with strings works",
  "error": null,
  "id": 1
}

I'm using http://www.gorillatoolkit.org/pkg/rpc.

Your Response fields are unexported. The names should be uppercase:

type Response struct {
    Sum     int
    Message string
}
