使用 Json 对象更新时，Alpaca setValue 不替换值

Question

使用 Alpaca js 我正在尝试使用 setValue 来更改字段值
我创建了这个简单的示例，它是一个单一的输入表单，当单击“更新输入”按钮时
输入应使用新值“NEW VALUE”进行更新
任何想法为什么它不起作用？

$(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 应该传递一个对象。

$(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
        }
      }
    }
  });
