Добрый день. Я использовала обработчик OnChange при изменении атрибута сущности

var oAttribute = crmForm.all.campaignid;
if (oAttribute.DataValue != null && oAttribute.DataValue[0] != null)
{

sEntityName = 'campaign';
GUID = oAttribute.DataValue[0].id;
sAttributeName = 'new_sourceid';

var authenticationHeader = GenerateAuthenticationHeader();

// Prepare the SOAP message.
var xml = "";
xml = xml+"<?xml version='1.0' encoding='utf-8'?>"+ 
"<soap:Envelope xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'"+
" xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'"+
" xmlns:xsd='http://www.w3.org/2001/XMLSchema'>"+ 
authenticationHeader+ 
"<soap:Body>"+ 
"<Retrieve xmlns='http://schemas.microsoft.com/crm/2007/WebServices'>"+ 
"<entityName>"+sEntityName+"</entityName>"+ 
"<id>"+GUID+"</id>"+ 
"<columnSet xmlns:q1='http://schemas.microsoft.com/crm/2006/Query' xsi:type='q1:ColumnSet'>"+ 
"<q1:Attributes>"+ 
"<q1:Attribute>"+sAttributeName+"</q1:Attribute>"+ 
"</q1:Attributes>"+ 
"</columnSet>"+ 
"</Retrieve>"+ 
"</soap:Body>"+ 
"</soap:Envelope>";

// Prepare the xmlHttpObject and send the request.
var xHReq = new ActiveXObject("Msxml2.XMLHTTP");
xHReq.Open("POST", "/mscrmservices/2007/CrmService.asmx", false);
xHReq.setRequestHeader("SOAPAction","http://schemas.microsoft.com/crm/2007/WebServices/Retrieve");
xHReq.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
xHReq.setRequestHeader("Content-Length", xml.length);
xHReq.send(xml);
// Capture the result.
var resultXml = xHReq.responseXML;

// Check for errors.
var errorCount = resultXml.selectNodes('//error').length;

if (errorCount == 0)
{
var result = resultXml.selectSingleNode("//q1:" + sAttributeName).nodeTypedValue;
crmForm.all.new_sourceid.value = result;
}

}

Но, к сожалению при изменении атрибута ничего не происходит. В чем может быть проблема?
