jquery-bootgrid - onclick 时在引导网格中显示/隐藏列 - 外部

Question

onclick 引导网格重新加载后，我无法隐藏显示/隐藏引导网格列。问题是它在第一次加载页面时有效，但在单击事件后我无法使其工作。任何帮助表示赞赏。

<th id="th_state" data-identifier="true"  data-column-id="state" data-visible="false">State</th>         

 $('#filter_group').change(function () {     
    $("#employee_grid").bootgrid("reload") 
    $("#th_state").attr("data-visible", "true")  ;    // Not working....
 });                   

$("#employee_grid").bootgrid({
                    ajax: true,
                    rowCount: [50, 100, 200, 300, 500],

                    columnSelection: true,

                            if ($(this).is(':selected')) {
                                citiesGroup.push({
