Making a callback with coolite from javascript

[petherson]

Hello, I?ve got a problem, when I was trying to do a post with Coolite. I´ve created ContextMenu with Ext (without Coolite) this ContextMenu has a delete option . When the user click it, I want to post the id to a page that will do the operation. I want to do using server-side Coolite controls(with ajax), and not with pure javascript. Is there a way?
Thank you.
Here is some pieces of my source code.

<script language="javascript" type="text/javascript" src="../../extjs/adapter/ext/ext-base.js"></script>
    <script language="javascript" type="text/javascript" src="../../extjs/ext-all.js"></script>
    <script language="javascript" type="text/javascript">
            var menuRowContext = new Ext.menu.Menu({
                    id: 'menuTeste',
                    items: [
                        {
                            text: 'Delete',
                            iconCls:'excluir',
                            handler: function()
                            {
                            }
                        }
                        ]
                });
            function linhaGrid(t,rowIndex,e)
            {
                var xy = e.getXY();
                menuRowContext.showAt(xy);
            }
    </script>

            <ext:GridPanel ID="GridPanel1" runat="server" StoreID="store1"
             Width="1000" Height="300" Frame="true" Title="Teste"
              ButtonAlign="Left">
                <Listeners>
                    <RowContextMenu Fn="linhaGrid" />
                </Listeners>
            </ext:GridPanel>
