动作后重新绘制数据表

我有问题让我的数据表刷新。我有一个按钮，调用更新脚本和确认消息之前，它做任何事情。这一切都很好，但是，我希望表刷新以获得新的结果。以下是我到目前为止写的。

function unapprove_link(data)
{
    var str = $(this).attr('title');
    var answer = confirm("Are you sure you want to UNAPPROVE this lead?");
    if (!answer) return false;
    $.post("actions/unapprove-lead.php",
    {'lead_id': data},
        function()
        {
            oTable.fnClearTable(0);
            oTable.fnDraw();
        }
);
}

            $(document).ready(function()
              {
        /*      // Unapprove Lead Alert
                $('.unapprove').live('click', function() {
                var str = $(this).attr('title');
                var answer = confirm("Are you sure you want to UNAPPROVE this lead?");
                oTable.fnDraw();
                if (!answer) return false;
                });
                // Delete Lead Alert
                $('.delete').live('click', function() {
                var str = $(this).attr('title');
                var answer = confirm("Are you sure you want to DELETE this lead?");
                oTable.fnDraw();
                if (!answer) return false;
                });
        */
                var anOpen = [];
                var oTable = $('#example').dataTable
                ({
