I am trying to rebind my RadGrid after I have performd some actions below is my ajax code that does some operations in server side:

var id = $(this).find("input[name$=hiddenID]").val();

                 $.ajax({
                    type: "POST",
                    url: "Details.aspx/DoStuff",
                    data: "{'id': '" + id + "'}",
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",

                    success: function (msg) {
                        if (msg.d == 'Sent') {
                            $.colorbox({ href: '/view.aspx?Id=' + id, iframe: true,});
                           GridRebind();
                        }
                    }

                });

To rebind on success I have got this javascript code:

function GridRebind() {
                        var masterTable = $find("<%= gd.ClientID %>").get_masterTableView();
                        masterTable.rebind();
                    }

But everytime I get $find(..)is null on var masterTable = $find("<%= gd.ClientID %>").get_masterTableView(); and it doesn't rebind the grid.

When researching I found out you need to put the following in Grid and set Grid datasource to something on page Init but still not working :

 <ClientSettings>
      <ClientEvents OnCommand="function(){}"  />
 </ClientSettings>
