Rebind Radgrid does not refresh when radwindow closes - asp.net

Question

I am trying to rebind my grid once a radwindow has been closed through master page. My grid is in a usercontrol in aspx page. In master page i have :
function CancelEdit() {
GetRadWindow().Close();
}
function CloseAndRebind() {
GetRadWindow().BrowserWindow.refreshGrid(); // Call the function in parent page
GetRadWindow().close(); // Close the window
}
function refreshGrid() {
$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");
}
and I have the following javascript in the user conrtrol:
<script type="text/javascript" language="javascript">
function refreshGrid() {
$find("<%= RadAjaxManager.GetCurrent(me.Page).ClientID %>").ajaxRequest("Rebind");
}
</script>
Once I close update the database in radwindow i register a javascript:
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "mykey", "CloseAndRebind();", True)
I can see my data source changing but the grid doesn't get updated. any suggestions?
EDIT ::
The structure is something like this:
I have master page which has the RadAjaxManager.
There is a main page which has a user control
Another user control inside above user control which has the RadGrid
Then there is an aspx page that opens as radwindow

Use the client-side API to rebind your grid, should be the correct way to do that:
In your child page:
function refreshGrid() {
$find("<%= YourGrid.ClientID %>").get_masterTableView().rebind();
}
To call a javascript function from the parent page, simply use this:
function CloseAndRebind() {
GetRadWindow().get_contentFrame().contentWindow.refreshGrid(); // Call the function in parent page
GetRadWindow().close(); // Close the window
}
