Is it possible to extract data directly from the original data instead of relying on filtered data?

While working on my project, I encountered an issue with a Kendo grid that has filtering functionality. The filtering itself is working perfectly fine, but I noticed that the data in the grid is not dynamically cleared when the filter is removed. Currently, the only way to clear the filtered data is by clicking a "clear" button. Is there a way to automatically clear the data without requiring the user to click the button?

         var grid = $("#grid").kendoGrid({
           dataSource: {
                       type  : "odata",
            transport      : {
                read: "http://demos.kendoui.com/service/Northwind.svc/Orders"
            },
            schema         : {
                model: {
                    fields: {
                        OrderID  : { type: "number" },
                        Freight  : { type: "number" },
                        ShipName : { type: "string" },
                        OrderDate: { type: "date" },
                        ShipCity : { type: "string" }
                    }
                }
            },
            pageSize       : 10
        },
        filterable: true,
        sortable  : true,
        pageable  : true,
        columns   : [
            {
                field     : "OrderID",
                filterable: false
            },
            "Freight",
            {
                field : "OrderDate",
                title : "Order Date",
                width : 100,
                format: "{0:MM/dd/yyyy}"
            },
            {
                field: "ShipName",
                title: "Ship Name",
                width: 200
            },
            {
                field: "ShipCity",
                title: "Ship City"
            }
        ]
    }).data("kendoGrid");

One solution that comes to mind is utilizing the parameterMap function in the 'read' type, allowing you to remove unnecessary filters and always send only the latest item in the filters array.
