How do I specify schema for TreeView HierarchicalDataSource using HtmlHelper?

[Greg]

I want to specify model schema, for example to specify "children" property. How do I need to change following Razor code to specify that "children" are stored in "subentities" property?

    @(Html.Kendo().TreeView()
        .Name("treeview")
        .DataTextField("Name")
        .DataSource(dataSource => dataSource
            .Read(read => read
                .Action("Employees", "TreeView")
            )
        )
    )

Does TreeView support schema customization?
