Why ListView is not working in WinJS?

我正在尝试使用Json进行ListView。但这显示错误为"WinJS.UI.ProcessAll（） 未定义;"。我错过了什么吗？

//default.html
    <body>
     <div data-win-control="WinJS.Binding.Template">
            <h2 data-win-bind="textContent: title"></h2>
            <img data-win-bind="src: imageUrl;alt: title" />
        </div>
       <div id="itemTemplateDiv" data-win-control="WinJS.UI.ListView" data-win-options="{
           itemDataSource: Matlus.Data.itemsBindingList.dataSource,
           itemTemplate: select('#itemtemplateDiv')
            }"></div>
    </body>

//default.js
(function(){
    var app = WinJS.Application;
    app.onactivated = function (args) {
        downloadDataAsync().then(function (items){
            assignToListView(items);
            WinJS.UI.processAll();
        });
    };
    function downloadDataAsync() {
        return WinJS.xhr({ url: "http://matlusstorage.blob.core.windows.net/membervideos/AllMovies.json" }).then(function (xhr) {
            var movies = JSON.parse(xhr.responseText);
            //"[{'"Category'":'"Sci-Fi'",'"ImageUrl'":'"StarWarsEpisodeIV.jpg'",'"Title'":'"Star Wars Episode IV: A New Hope'",'"Year'":1977}
            //({title: item.Title, imageUrl: "http://matlusstorage.blob.core.windows.net/membervideos/" + item.imageUrl, category: item.category, year:});
            var items = [];
            for (var i = 0; i < movies.length; i++) {
                var item = movies[i];
                items.push({ title: item.Title, imageUrl: "http://matlusstorage.blob.core.windows.net/membervideos/" + item.ImageUrl, category: item.Category, year: item.Year });
            }
            return items;
        });
    }
    function assignToListView(items) {
        Matlus.Data.itemsBindingList =  new WinJS.Binding.List(items);
    }
    WinJS.Namespace.define("Matlus.Data", {
        itemsBindingList: undefined, 
    });
    app.start();
})();

尝试使用小写的 p. ;) WinJS.UI.processAll()
