mui-popover中放入input在微信上无法获取焦点

<div id="edit" class="mui-popover mui-popover-action mui-popover-bottom">
<ul class="mui-table-view">
<li class="mui-table-view-cell ">
<div class="mui-dtpicker-header">
<button id="btn-cancel" class="mui-btn mui-pull-left">取消</button>
<button id="btn-ok" class="mui-btn mui-btn-blue mui-pull-right" style="margin-right: 0px;" data-cname="">确定</button>
</div>
<li class="mui-table-view-cell mui-input-row">
<input type="text" class="mui-input-clear" placeholder="请填写" id="cvalue"> </li>
</ul>
</div>

在IE、chrome下调试正常，在微信上无法获取输入焦点
