Dynamically bind GridView inside Modal Popup based on Button clicked using jQuery in ASP.Net

In continuation of my earlier project--- I have three panels and in one of panel I have one gridview with binding to datatable fields. Gridview is being displayed on click of a button in popup window using Java script. I like to use same popup window and gridview on click of the two buttons but with different set of datatable fields. I could not succeeded in binding different sets of datatable fields according to the button pressed and displaying in gridview I am also having show and hide option of button on mouse over on TextBox8, but not working. If posible please suggest rectification and necessary coding. Thanking you in advance

<script type="text/javascript">
    $(function () {
        $("[id*=TextBox8] td").bind("mouseover", function () {
            $(this).closest("tr").find("[id*=btn1]").show();
        });
        $("[id*=TextBox8] td").bind("mouseout", function () {
            $(this).closest("tr").find("[id*=btn1]").hide();
        });
    });
    $(function () {
        $("[id*=btn1]").click(function () {
            ShowPopup1();
            return false;
        });
    });
    $(function () {
        $("[id*=btn2]").click(function () {
            ShowPopup2();
            return false;
        });
    });
    function ShowPopup1() {
        $("#dialog").dialog({
            title: "btn1 details",
            width: 450,
            buttons: {
                Ok: function () {
                    $(this).dialog('close');
                }
            },
            modal: true
        });
    }
    function ShowPopup2() {
        $("#dialog").dialog({
            title: "btn2 details",
            width: 450,
            buttons: {
                Ok: function () {
                    $(this).dialog('close');
                }
            },
            modal: true
        });
    }
</script>

<div id="dialog" style="display: none">
    <asp:GridView ID="gvdetails1" runat="server" AutoGenerateColumns="False">
        <Columns>
            <asp:BoundField DataField="column1" HeaderText="column 1 details" ItemStyle-Width="80" />
            <asp:BoundField DataField="column2" HeaderText="column 1 qty" ItemStyle-Width="25" />
        </Columns>
