Open Window and preload data

[Neil]

Hi,
I am upgrading from Telerik extensions. The code used to open a window and set the datasource for the grid on that page was:

function openTrainWind(trainID) {
            var window = $("#trainWindow").data("kendoWindow");
            window.ajaxRequest("/Trains/_Trains/", { _trainID: trainID });
            window.center().open();
        }

The code has been upgraded to work with Kendo but produces the error "Uncaught TypeError: undefined is not a function"
How would this code need to change to work with Kendo.

Thanks
