I want to use jQuery to call a asmx web service to validate user logins. The Ajax call is successful but I don't get any results. Can anyone help to find where the problem is?

Here is the web service:
http://54.245.105.127/UACServices/GS...p=validateUser

Here is the code for the call:
Code:
$('#loginForm').submit(function(e) {
                e.preventDefault();
				var username = $('input[name="username"]').val();
				var password = $('input[name="password"]').val();
				var tablename = "tbl_CODNRUSERS";
				var userInfo = '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><validateUser xmlns="http://tempuri.org/"><username>'
                    + username + '</username><password>'
                    + password + '</password><tablename>'
                    + tablename + '</tablename></validateUser></soap:Body></soap:Envelope>';
                $.ajax({
                    url: "http://localhost/UACServices/GSaaS.asmx?op=validateUser",
					type: "POST",
                    contentType: "text/xml; charset='utf-8'",
                    
                    data: userInfo,
                    success: function(data) {                        
						console.log(data);
                    },
                    error: function(errMsg)
                    {
                        console.log("error: " + errMsg);
                    }
                });
				return false;
            });
