EXTJS:如何把后台返回的json数据中的值赋给text

new Ext.panel.Panel({
title: 'test',
renderTo: Ext.getBody(),
width: 580,
height: 500,
frame: true,
//layout: 'fit',
listeners: {
afterrender: function (o) {
Ext.Ajax.request({
url: "ASHX/UserSession.ashx",
method: "POST",
success: function (response, options) {
var res = response.responseText;
alert(res);//成功返回json后，如何赋值给text
}
});
}
},
items: [{
xtype: 'textfield',
id:'UserNames',
name: 'name',
fieldLabel: '姓名',
},
后台返回的json数据是{'UserName':'周杰伦','Branch':'中国分公司','Depart':'公关部'}
