<script>
    $("#dropdowntree").kendoDropDownTree({
        valuePrimitive: true,
        dataTextField: "name",
        dataValueField: "id"
    });
    var viewModel = kendo.observable({
        selectedProductId: null,
        products: [
            { id: 1, name: "Coffee" },
            { id: 2, name: "Tea" },
