我想动态设置面板标题.而以下似乎不起作用!有任何想法吗？提前致谢!

Ext.create('Ext.panel.Panel', {
       id: 'p0',
       title: 'Hello World',
       width: 200,
       html: '<p>Lorem ispsum doler sit</p>',
       renderTo: Ext.getBody()
});

Ext.getCmp('p0').title = 'Bye World'; //does not work!    
Ext.getCmp('p0').header.title = 'Bye World'; //does not work either!
