要用api来添加，直接用jquery方法肯定不行了，UI结构都不一样

 add    options     Add a new panel. By default the added panel will become selected. To add a unselected new panel, pass the 'selected' property and set it to false.

Code example:

$('#aa').accordion('add', {
    title: 'New Title',
    content: 'New Content',
    selected: 

动态添加调用：
$('#module').accordion('add', {
title: '新标题',
content: 'aaaaaaaaa',
selected: false
});
