Getting null from GlideAjax

[samadam]

Script Include: 

var AUtils = Class.create();

AUtils.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    checkEmail: function() {

        var email1 = this.getParameter('sysparam_useremail');

       var uprofile = new GlideRecord('sys_user');

        uprofile.addQuery('email', email1);

        uprofile.query();

        if (uprofile.next()){

            answer = true;

        } else answer = false;

        return answer;

      },

    type: 'AUtils'

});

Client scripts:

        var ap = new GlideAjax('AUtils');

        ap.addParam("sysparam_name", "checkEmail");

        ap.addParam('sysparam_useremail', email_d);

        ap.getXML(EmailResponse);

    }

            function EmailResponse(response) {

                 if(response){

                   var answer = response.responseXML.documentElement.getAttribute("answer");  

                    if(answer){

                        var data = JSON.parse(answer);

                                        }

                    else alert("No answer");

                 }

I keep getting null value. Not sure what is wrong. Any ideas?
