How to refresh mvc wrapper grid?

[Behrad]

I have defined a grid like this:
@(Html.Kendo().Grid(Model)
             .Name("OnlineVisitors")
             .Columns(c =>
                {                  
                    c.Bound(p => p.DurationInMinute).Title("duration");
                    c.Bound(p => p.PersianStartDate).Title("start time");
                    c.Bound(p => p.IP).Title("IP Address");
                })
             .DataSource(datasource =>
                 datasource.Ajax()
                           .Read(read => read.Action("JsonList", "OnlineVisitors", routeKeyValues))
             )
)
And now i want to refresh the grid in JavaScript code,after an Ajax call to server,that do something with data source i'm using.any help will be appreciated.

$('#OnlineVisitors').data('kendoGrid').dataSource.read();
