I found solution .... It is not working with Generic Handler but it works fine with webservice without any problem.

[WebMethod]
    [ScriptMethod(UseHttpGet = false, ResponseFormat = ResponseFormat.Json)]     
    public Handler1.TicketResponse HelloWorld()
    {
        var ticketResponse = new Handler1.TicketResponse();
        ticketResponse.AddedCount = 23;

        // All tickets were available and were added to the cart
        ticketResponse.Success = true;
        ticketResponse.SuccessItems = new List<Handler1.SuccessfullItem>
                                          {
                                              new Handler1.SuccessfullItem()
                                                  {

                                                      OrderItemId = 1,
                                                      Title = "【桃姐與我】舞台劇（粵語）粵語）"
                                                  }
                                          };

        return ticketResponse;
    }
