¿Cómo accedo a un campo de ViewModel desde la definición de una columna de Kendo Grid MVC?

¿Cómo accedo al campo c => c.IsExpired que está debajo en lugar del marcador >>> ISEXPIRED <<<?

@(Html.Kendo().Grid()
    .Name("ordersGrid")
    .Columns(columns =>
    {
        columns.Template(@)
            .ClientTemplate(AdminDeleteEditTemplate().ToHtmlString())

        columns.Bound(c => c.ResellerName).ClientTemplate("#= ResellerID ? ResellerName : '' #");

        columns.Bound(c => c.Date).Format("{0: MMM d, yyyy}").HtmlAttributes(new { @class = "text-right" });
