如何在kendo甘特图中动态添加行？

Question

我需要动态地向Kendo Gantt图表添加行（有点像添加新任务）。 我将新行添加到dataSource，但新添加的行未反映在UI中。我尝试刷新甘特图，但没有运气。添加k-rebind有效，但我不想使用k-rebind选项。

function injectRow() {
    $scope.myGanttOptions = ganttServices.injectRow($scope.myGanttOptions);
    console.log($scope.myGanttOptions); //$scope.myGanttOptions is having the newly injected row, but it is not seen in the UI.

    //  refreshing the gantt chart does not inject the row.(even after trying it in timeout)
    $timeout(function() {
        $('#ganttID').getKendoGantt().dataSource.read();
        $('#ganttID').getKendoGantt().refresh();
    },100);
}
