Hi,

In order to delay the filter execution when using template you would need to add that delay to the custom logic. You can wrap the code in the ProvinceNameChenged handler in setTimeout() and specify the delay.

function ProvinceNameChenged(sender, args) {
    setTimeout(function () {
        var gv = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");
        if (args.get_newValue() == "") {
            gv.filter("ProvinceName", null, "NoFilter");
            return;
        }
        gv.filter("ProvinceName", args.get_newValue(), "StartsWith");
    }, 1000);
}
