   "RequestType": "UserAdd",
   "RequestCreatedDate": "2016-03-25T00:13:21Z"

Pass operations array to the transform

  var operate= [
    {
      run: function () {
        var d = new Date();
        var n = d.toJSON().toString();
 
        return n;
      },
      on: "RequestCreatedDate"
    },
    {
      run: function () {
        var d = new Date();
        var n = d.toJSON().toString();
 
        return n;
      },
      on: "RqMsgCreatedDt"
    }
  ];
 
  var result = jsonTojson.transform(data, template, operate);
