Change a record with a REST WebService

I'm trying to change my bank's registry via a webservice rest in java, the tests in webservice worked, but on the client I'm having trouble working.

Note: I use Delphi XE8 (Client) and Netbeans (WS)

WS:

@PUT
    @Consumes(MediaType.APPLICATION_JSON)
    @Path ("Banco/put/{codigo}")
    public String putBanco(@PathParam("codigo") int codigo, String nome) {

        BancoCTR ctr = new BancoCTR();
        ctr.setBcoNome(nome);

        BancoDAO dao = new BancoDAO();
        String resposta = dao.editBanco(codigo, ctr);

        Gson gson = new Gson();
        return gson.toJson(resposta);
    }

When I do the test, it is working:

ButIhaveaquestion,publicStringputBanco(@PathParam("codigo") int código, String nome) PathParam causes me to have access to this variable "code", but how will I have access to variable "name" in the client?

Client:

procedure TForm1.btn2Click(Sender: TObject);
var
  LJson: TJSONValue;
begin
  rstrspns1.RootElement := 'object';

  with rstrqst1 do
  begin

    Resource := '/Banco/put/{codigo}';
    Method := rmPUT;

    Params.AddUrlSegment('codigo', edt1.Text);
    Params.AddItem('nome', edt2.Text, TRESTRequestParameterKind.pkGETorPOST);
    Execute;

    LJson := Response.JSONValue As TJSONObject;

    MessageDlg(LJson.ToString, mtInformation, [mbOK], 0);
  end;
end;

I thought of using Params.AddItem('nome', edt2.Text, TRESTRequestParameterKind.pkGETorPOST); to get access to variable name, but when I run I get errors:
