Problem with passing xml data to webservice and return the xml file as result back from ajax -jquery call in clientside

Question

I have jquery ajax call to webservice for which i am passing xml parameters as data ,when i run the code the flow is not reaching webservice GetList method at all, can anyone track what may be the problem should i make any changes to my webconfig file or refer any latest jquery file to get the code running sucessfully

    $.ajax({
                    type: "POST",
                    async: false, 
                    url: "/blkseek2/JsonWebService.asmx/GetList",
                    datatype:"xml",
                    data:"<?xml version='1.0'?><keyword1>"+keyword1+ "</keyword1><streetname>"+address1+ "</streetname><lat>"+lat+"</lat><lng>"+lng+ "</lng><radius>"+radius+"</radius>" ,
                    contentType: "application/xml; charset=utf-8",
                  //  processData: false,
                    failure: function(XMLHttpRequest, textStatus, errorThrown) 
                         { ajaxError(XMLHttpRequest,textStatus, errorThrown); },
                    success: function(xml) 
                     { ajaxFinish(xml); }


//                  success: ajaxCallSucceed,
//                  dataType: "xml",
//                  failure: ajaxCallFailed
                });
                });

This is my method in webservice file

 public XmlDocument GetList(string keyword1, string streetname, string lat, string lng, string radius)
    {
        XmlDocument xmldoc= CreateXML( keyword1,streetname,lat,lng,radius);


        return xmldoc;

    }
