Alpaca setValue not replacing the value when updating with Json object

Question

Using Alpaca js I am trying to use setValue to change a field value
I have created this simple example its a single input form, that when clicking "update input" button
the input should be updated with new value, "NEW VALUE"
Any Idea why is it not working?

$(document).ready(function(){
	createForm("firstName","First Name","OLD VALUE","string");  
});


function updateForm(){
 alert(JSON.stringify($("#alpacaForm").alpaca().getValue(), null, "  "));
 $("#alpacaForm").alpaca().setValue('{"fieldName": "NEW VALUE"}');
}
function createForm(fieldName,fieldLable,fieldVal,fieldType){

$("#alpacaForm").alpaca({
    "data": { fieldName: fieldVal },
    "schema": {
        "type": "object",
        "properties": {
            fieldName: {
                "type": fieldType,
                "title": fieldLable
            }
        }
    }
});

}

<div id="alpacaForm" ></div>
<button onclick="updateForm()">update input</button>

Form.setValue should be passed an object.

$(document).ready(function() {
  createForm("firstName", "First Name", "OLD VALUE", "string");
});


function updateForm() {
  alert(JSON.stringify($("#alpacaForm").alpaca().getValue(), null, "  "));
  $("#alpacaForm").alpaca().setValue({"firstName": "NEW VALUE"});
}

function createForm(fieldName, fieldLable, fieldVal, fieldType) {

  $("#alpacaForm").alpaca({
    "data": {
      [fieldName]: fieldVal
    },
    "schema": {
      "type": "object",
      "properties": {
        [fieldName]: {
          "type": fieldType,
          "title": fieldLable
        }
      }
    }
  });
