        var currentSort = table.fnSettings().aaSorting;
        // do something here
    })
    .on('search.dt', function () {
        var value = $('.dataTables_filter input').val();
        // do something here
    })
    .on( 'init.dt', function () {
        // fired when DataTables has been completely loaded.
        firstTimePageLoad = false;
    } )
    .DataTable({
        paging: false,
        ordering: true,
        fixedHeader: true,
        "search": {
            "search": searchText
