How to print(or show info msg) an array using getXMLAnswer method through client script?

[KM SN]

I just want to send two details of caller to an array and bringing them back to client script and there using Client script i need to show the array whenever the caller field changes. but i am getting msg as below and i am adding script too.

Client Script:

var cid = g_form.getValue('caller_id');

var ga = new GlideAjax('gettingcallerdetails');

ga.addParam('sysparm_name','callerdetails');

ga.addParam('sysparm_caller', cid);

ga.getXMLAnswer(details);

function details(response){

        //var res = JSON.parse(response);

        var res = [response.toString()];

        g_form.addInfoMessage('Hi'+res);

        }

Script Include:

var gettingcallerdetails = Class.create();

gettingcallerdetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    callerdetails: function() {

        var abc = this.getParameter('sysparm_caller');

        //var obj = {};

        var obj = [];

        var utable = new GlideRecord('sys_user');

        if (utable.get(abc)) {

            //obj.phone = utable.getDisplayValue('mobile_phone');

            //obj.email = utable.getDisplayValue('email');

            obj.push(utable.getDisplayValue('mobile_phone'));

            obj.push(utable.getDisplayValue('email'));

            gs.addInfoMessage('SC :' + obj);

        }

        // return JSON.stringify(obj);

        return obj;

    },

    type: 'gettingcallerdetails'

});

Hi @KM SN ,

I'm able to solve your problem in my PDI please check below 

Client script : 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    //Type appropriate comment here, and begin script below
    var cid = g_form.getValue('caller_id');
    var ga = new GlideAjax('gettingcallerdetails');
    ga.addParam('sysparm_name', 'callerdetails');
    ga.addParam('sysparm_caller', cid);
    ga.getXMLAnswer(details);

    function details(response) {
        var res = JSON.parse(response);
        g_form.addInfoMessage('Hi' + res);
    }


}

Script Include : 

callerdetails: function() {
        var abc = this.getParameter('sysparm_caller');
        //var obj = {};
        var obj = [];
        var utable = new GlideRecord('sys_user');
        if (utable.get(abc)) {
			var mobile = utable.getDisplayValue('mobile_phone')+"";
			var email = utable.getDisplayValue('email')+"";
            obj.push(mobile);
            obj.push(email);
            gs.addInfoMessage('SC :' + obj);
        }
        return JSON.stringify(obj);
    },
