How to fiddle an easy OnDemandList (dgrid)?

I have tried to create a very simple jsfiddle to test an OnDemandList (sitepen/dgrid). But it does not render any rows. Does anybody have an idea what I have done wrong? Is it that a simple dstore/Memory does not offer methods like fetchRange? The jsFiddle can be found here: http://jsfiddle.net/rbeqqr2g/25/

require({
    packages: [
        {
            name: 'dgrid',
            location: '//cdn.rawgit.com/SitePen/dgrid/v0.3.16'
        },
        {
            name: 'xstyle',
            location: '//cdn.rawgit.com/kriszyp/xstyle/v0.2.1'
        },
        {
            name: 'put-selector',
            location: '//cdn.rawgit.com/kriszyp/put-selector/v0.3.5'
        },
        {
            name: 'dstore',
            location: '//cdn.rawgit.com/SitePen/dstore/master'
        }
    ]
}, [
    'dgrid/OnDemandList',
    'dstore/Memory',
    'dojo/dom',
], function(OnDemandList, Memory, dom) {
    var data = [
        { id: 1, name: 'Peter' },
        { id: 2, name: 'Paul' },
        { id: 3, name: 'Mary' }
    ];
    var store = new Memory({ 
        data: data 
    });
    var list = new OnDemandList({
        collection: store,
        minRowsPerPage: 5,
        noDataMessage: "Keine Daten vorhanden",
        renderRow: function (object, options) {
            console.log("Zeile wurde gerendert.")
            var div = document.createElement('div');
            div.appendChild(document.createTextNode(object.name));
            return div;
        }
    }, dom.byId('list'));
    list.startup();
});

You're using the most recent dstore, but an old dgrid. The < 1.x versions of dgrid did not support dstore, you can use a regular dojo/store/Memory instead. In dgrid < 1.x, you also needed a store property instead of collection.

require({
    ...
}, [
    'dgrid/OnDemandList',
    //'dstore/Memory',
    'dojo/store/Memory',  // < --- regular dojo/store
    'dojo/dom',
], function(OnDemandList, Memory, dom) {
    ...
    ...
    var list = new OnDemandList({
        //collection: store,
        store: store,      // <--- store property
        ...
    }, dom.byId('list'));
    list.startup();
});

Alternatively, unless you're stuck with dgrid 0.3.x, you can also simply use the modern dgrid:

{
    name: 'dgrid',
    location: '//cdn.rawgit.com/SitePen/dgrid/v1.1.0'
    //location: '//cdn.rawgit.com/SitePen/dgrid/v0.3.16'
},
