JQGrid搜索按钮不起作用

Question

我有一个JQgrid，我试图将datepicker放入我的一个colmodel中 如

colModel: [{
    name: 'Business Date',
    index: 'Business Date',
    width: 90,
    sorttype: 'string',
    align: 'center',
    datefmt: 'Y-m-d',
    editable: true,
    search: true,
    stype: 'text',
    searchoptions: {
        dataInit: function(elem) {
            /*jQuery*/
            $(elem).datepicker({
                showButtonPanel: true,
                changeMonth: true,
                changeYear: true

            });
        }
    }
}]

这是我的navgrid

navGrid('#pager', {
    edit: false,
    add: false,
    del: false,
    search: true,
    refresh: true
});

另外，这是我的jQgrid配置

<script src="./scripts/common.js" type="text/javascript"></script>
<script type="text/javascript" language="javascript" src="./scripts/jquery-1.6.3.js"></script>
<script type="text/javascript" language="javascript" src="./scripts/grid.locale-en.js"></script>
<script type="text/javascript" language="javascript" src="./scripts/jquery.jqGrid.min.js"></script>

<link href="./css/redmond/jquery-ui-1.10.3.custom.css" rel="stylesheet" type="text/css"/>
<link href="./css/ui.jqgrid.css" rel="stylesheet" type="text/css" />

现在，当我点击搜索按钮时，没有任何反应。有没有办法通过在某处发出警报来找出搜索按钮尝试做什么？如何访问搜索按钮的实际功能定义？我还有一些其他屏幕在searchoptions colmodel中没有datepicker，但搜索似乎工作正常。我的语法有问题吗？

修改

这是整个网格代码
