    var events = ["app.record.create.change." + CHECKALL, "app.record.edit.change." + CHECKALL];

    kintone.events.on(events, function(event) {
        var record = event.record;
        var changes = event.changes.field.value;

        if (changes[0] === "check all") {
            record[CHECKBOX].value = ["sample1", "sample2", "sample3", "sample4", "sample5"];
        } else {
            record[CHECKBOX].value = [];
        }
        return event;
    });
}());
