auto populate caller details when caller field changes but it was note populating can any one help

[ArunaTunga]

Client script: table is incident filed name is caller

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

   if (isLoading || newValue === '') {

      return;

   }

   //Type appropriate comment here, and begin script below

   var ga= new GlideAjax('UserDetails');

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

   ga.addParam('sysparm_user',newValue);

   ga.getXML(function(response){

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

    var data = JSON.parse(answer);

    g_form.setValue('u_caller_department',data.department);

    g_form.setValue('u_caller_email',data.email);

    g_form.setValue('u_caller_manager',data.manager);

   });

}

Script includes (enabled client callable):

var UserDetails = Class.create();

UserDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getUserDetails : function(){

    var userId = this.getParameter('sysparm_user');

    var details ={};

    var gr= new GlideRecord('sys_user');

    if(gr.get(userId)){

        details.department = gr.department.getDisplayValue();

        details.manager=gr.manager.getDisplayValue();

        details.email = gr.email+'';

    }

     return JSON.stringify(details);

    },

    type: 'UserDetails'

});

@ArunaTunga ,

Script include:

var UserDetails = Class.create();

UserDetails.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getUserDetails: function () {

        var userId = this.getParameter('sysparm_user');

        var details = {};

        var gr = new GlideRecord('sys_user');

        if (gr.get(userId)) {

            details.department = gr.department.toString(); // sys_id

            details.manager = gr.manager.toString();       // sys_id

            details.email = gr.email.toString();

        }

        return JSON.stringify(details);

    },

    type: 'UserDetails'

});

Client Script:

//Type appropriate comment here, and begin script below

   function onChange(control, oldValue, newValue, isLoading, isTemplate) {

    if (isLoading || !newValue) {

        return;

    }

    var ga = new GlideAjax('UserDetails');

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

    ga.addParam('sysparm_user', newValue);

    ga.getXML(function (response) {

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

        var data = JSON.parse(answer);

        g_form.setValue('department', data.department);

        g_form.setValue('manager', data.manager);

        g_form.setValue('email', data.email);

    });

}
