The value returned is wrapped in xml

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a webservice method in asp.net v3.5 to consume the edit function. The 
webservice method should only return the value supplied in the request.
2. Edit a cell in a datatable
3. I am getting an error alert because the value returned is wrapped in xml

What is the expected output? What do you see instead?
The webservice method is as follows:
<code>    
    [WebMethod]
    public string UpdateUser(string value, string id, string rowId, string         columnPosition, string columnId, string columnName)
    {
        return value;
    }
</code>
The value being posted in the editable request is correct but the return value 
is wrapped in xml i.e. "<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">help</string>"
What version of the product are you using? On what operating system?

Version 1.3 of editable
Version 1.9.4 of datatables
