Jquery Mobile 中响应式表格问题

代码如下：
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://apps.bdimg.com/libs/jquerymobile/1.4.5/jquery.mobile-1.4.5.min.css">
<script src="http://apps.bdimg.com/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="http://apps.bdimg.com/libs/jquerymobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
<script>
$(document).on("pagecreate","#pageone",function(){
$("#test").html("<tr><td>1</td><td>Alfreds Futterkiste</td><td>Maria Anders</td><td>Obere Str. 57</td><td>Berlin</td><td>12209</td><td>Germany</td></tr>");
});
</script>
</head>
<body>

<div data-role="page" id="pageone">
<div data-role="header">
<h1>列切换表格</h1>
</div>
<div data-role="main" class="ui-content">
<table data-role="table" data-mode="columntoggle" class="ui-responsive" data-column-btn-text="点我显示或隐藏列!" id="myTable">
<thead>
<tr>
<th data-priority="6">CustomerID</th>
<th>CustomerName</th>
<th data-priority="1">ContactName</th>
<th data-priority="2">Address</th>
<th data-priority="3">City</th>
<th data-priority="4">PostalCode</th>
<th data-priority="5">Country</th>
</tr>
</thead>
<tbody id="test">
<tr><td>1</td><td>Alfreds Futterkiste</td><td>Maria Anders</td><td>Obere Str. 57</td><td>Berlin</td><td>12209</td><td>Germany</td></tr>
</tbody>
</table>
</div>
<div data-role="footer">
<h1>底部文本</h1>
</div>
</div>
</body>
</html>
这段代码中如果注释掉 $("#test").html("<tr><td>1</td><td>Alfreds Futterkiste</td><td>Maria Anders</td><td>Obere Str. 57</td><td>Berlin</td><td>12209</td><td>Germany</td></tr>"); 赋值这段，点击显示隐藏列按钮可以对表格的头和内容都起作用。
直接写html就可以，用jquery的html()函数赋值就不行，为什么呢？
