Thank you for reply after a week of waiting, I also comment this case on SPA page, but no answer.

I have correct to be the following code, but still the same. When I use this on browse data exist http://localhost:3713/api/DataServices/GetDeliveriesForToday, but when I run after I modified, still do not show my allert. Here the code I modified:

@using DeliveryTracker.Controllers
@section featured {
    <section class="featured">
        <div class="content-wrapper">
            <hgroup class="title">
                <h1>Welcome to my Single Page Application</h1>
            </hgroup>
        </div>
    </section>
}

@(Html.UpshotContext().DataSource<DataServicesController>(x => x.GetDeliveriesForToday()))

<script type="text/javascript">

    $(function () {
        var dataSource = upshot.dataSources.GetDeliveriesForToday;
        dataSource.refresh(function (results) {
            alert(results);
        });
    });
</script>
