无法为WinJS Listview调用项目的样式

Question

我想在WinJS Listview中调用项目时更改项目的背景颜色。这是一个Windows Phone 8.1应用程序。我已经尝试了这里记录的内容......

我的ListView没什么不寻常的，非常香草......

 <div id="itemTemplate" data-win-control="WinJS.Binding.Template">
    <div class="itemContainer">
        <div>
            <div data-win-bind="innerText: name"></div>
            <div data-win-bind="innerText: timestamp"></div>
        </div>
    </div>
</div>

<div id="listView"
   data-win-control="WinJS.UI.ListView"
   data-win-options="{ itemTemplate: select('#itemTemplate'),
      layout: {type: WinJS.UI.ListLayout},
      selectionMode: 'single',
      tapBehavior: 'invokeOnly' }">
</div>
