jquery mobile ajax加载后不能展开

各位大神帮忙看一下感激不尽
这是静态页面写的代码
可以正常的展开 收起

 <div data-role="collapsible" data-collapsed-icon="arrow-d" data-expanded-icon="arrow-u" class="ui-collapsible  ui-collapsible-inset ui-first-child ui-collapsible-collapsed">
    <h6 class="ui-collapsible-heading ui-collapsible-heading-collapsed">

                <span class="ui-btn-text">潇洒  2013-12-3  早上
                    <span class="ui-collapsible-heading-status"> click to expand contents
                    </span>
                </span>
                <span class="ui-icon ui-icon-shadow ui-icon-arrow-d">&nbsp;

    <div class="ui-collapsible-content ui-collapsible-content-collapsed" aria-hidden="true">

                <ul data-role="listview" class="order-content ui-listview">

                        <div data-corners="true" data-shadow="true" data-iconshadow="true" data-wrapperels="span" data-theme="b" data-inline="true" data-mini="true" data-disabled="false" class="ui-submit ui-btn ui-btn-up-b ui-shadow ui-btn-corner-all ui-mini ui-btn-inline" aria-disabled="false"><span class="ui-btn-inner"><span class="ui-btn-text">拒绝</span></span><button type="submit" value="no" data-inline="true" data-mini="true" data-theme="b" class="ui-btn-hidden" data-disabled="false">拒绝</button></div>
                    </form>
                    </li>
                </ul>
            </div></div> 

但是用ajax加载 看起来也一个样子 但是点击没有展开的效果了 也展不开
是不是jquery mobile有什么特性需要禁用？或者是其他原因？

jquery mobile通过其他方式加载生成页面元素后是需要刷新的。
这里有常用的刷新方式
