Accessing the JSON response within onSubmitComplete

Hi,

I'm using server side processing and I'm trying to access a specific value from the JSON response after updating a record. In my initialisation I'm using the following:

editor.on('onSubmitComplete', function ( e, json, data ) {
  alert('howdy');
});

I know the event is being triggered as the alert is showing. My JSON is of the format:

{
  "id": "id_value",
   "row": {
      "rCREATEDATE": "value_in_here",
      "rCREATEDATEF": "value_in_here",
      "rCREATETIME": "value_in_here",
      "sPMTAMT": "value_in_here",
      "sPMTTYPE": "value_in_here",
      "sPMTMEMCLASS": "value_in_here",
      "sPMTREF": "value_in_here"
    }
}

I have included the full initialisation code below. Any help greatly appreciated.

Thanks
