Как получить значение флажков в сетке кендо

У меня есть сетка кендо, которая содержит два типа строк: одна относится к классу css k-master-row, который появляется при первоначальной загрузке сетки, а другая - к классу css k-detail-row k-alt, который появляется при щелчке раскрывающегося списка, по сути, функционирует как деталь для каждого мастера ряд. В каждой основной строке есть флажок, значение которого необходимо получить:

<td class = "" role = "gridcell"><input id = "TOC_ckbx" name = "TOC_ckbx" type = "checkbox" value = "15" checked = "checked" class = "chkbx"></td>

Первоначально я получал значение флажка в событии изменения следующим образом:

$("#sectionGrid .k-grid-content").on("change", "input.chkbx", function (e) {
            var dataItem = $grid.dataItem($(e.target).closest("tr"));            
            dataItem.set("TocShow", this.checked);
});

Этот код работал, но поскольку он проверяет все флажки ввода во всех дочерних элементах, он также отслеживал изменения в двух флажках в сетке деталей под ним:

<tr data-uid = "34d19927-c356-4d6d-9e00-5b470fe369eb" role = "row">
<td role = "gridcell"><input class = "k-checkbox" data-role = "checkbox" id = "0b1e4591-88c0-4796-aa62-1c9482005be1" aria-label = "Select row" aria-checked = "false" type = "checkbox"><label for = "0b1e4591-88c0-4796-aa62-1c9482005be1" class = "k-checkbox-label k-no-text">​</label></td>
<td class = "" role = "gridcell"><input id = "FirstRun" name = "FirstRun" class = "chkbx" type = "checkbox" checked = ""></td>
<td class = "" role = "gridcell"><input id = "SecondRun" name = "SecondRun" type = "checkbox" checked = "" class = "chkbx"></td>
</tr>

Затем я попытался получить каждый из флажков #TOC_ckbx в главной строке по идентификатору, используя следующий идентификатор, но по какой-то причине отслеживаются только изменения флажка в первой строке, а не какие-либо флажки в других строках:

 $("#TOC_ckbx.chkbx").change(function (e) {
            var dataItem = $grid.dataItem($(e.target).closest("tr"));
            dataItem.set("TocShow", this.checked);
        });

Каков правильный селектор JQuery, который нужно использовать, чтобы получить значение всех флажков оглавления в событии изменения?
