Get Full Name using People Control

Hi,

I've people control on my form, and I want to return full name from this control, but it doesn't appear full name, it always 'domainname\username'

I tried using javascript 

NWF$(document).ready(function () {
    NWF$('#' + varTravellerName).click(function () {
         var travellerAD = NWF$('#' + varTravellerName).val();
         var userName = getFullName(travellerAD);
         NWF$('#' + varADFullName).val(userName+' - ');
    });
}); 

In which varTravellerName is Person control Id I passed to javascript and varADFullName is Textbox control Id I passed to javascript. 

I've tried also using     NWF$('#' + varTravellerName).change(function () { , and also it didn't work.

Anybody know what function I should use for event change on NWF People??
