Kendo Grid is not refreshing after switching tabstrip

[Priyojit]

In my project there are two tabstips, each containing a kendo grid. The tabstrip is located in a aspx page and two tabstrip hold the html pages. The grids are located in these html pages. I've written the code to load the tabstrip like following,

$(document).ready(function () {
            $("#tabstrip").kendoTabStrip({
                animation: { open: { effects: "fadeIn"} },
                contentUrls: [
                        'Page1.htm',
                        'Page2.htm',
                    ]
            });
        });

Now at the first time it is running ok, But the problem comes, in the grid of 1st tab when i made some changes, which i expected to get reflected in the grid of 2nd tab, but it is not happening as the grid inside tab2 refreshes only once.
How can I do this? Please help.
