I have a nested content list (meetingItemDayTimes) inside nested content list (meetingDatesAvailable).

I want to set a checkbox to true on the each time item. But I can't for the life of me get it to work.

The structure is like:

My code is this:

var mainpage = contentService.GetById(1057);
var dateItems = Umbraco.Content(parentNode).Value<IEnumerable<IPublishedElement>>("meetingDatesAvailable");
var ncItems = new JArray();
var ncDateItems = new JArray();
var ncTimeItems = new JArray();

if (dateItems != null && dateItems.Any())
{
   foreach (var dateItem in dateItems)
   {
       var ncDateItem = new JObject();
       ncDateItem.Add("key", dateItem.Key.ToString());
       ncDateItem.Add("ncContentTypeAlias", dateItem.ContentType.Alias);
       ncDateItem.Add("meetingItemDay", dateItem.Value<string>("meetingItemDay", fallback: Fallback.ToDefaultValue, defaultValue: null));

       var times = dateItem.Value<IEnumerable<IPublishedElement>>("meetingItemDayTimes");

       foreach (var time in times)
       {
           var ncTimeItem = new JObject();

                        if (time.Key.ToString() == itemKey)
                        {
                            ncTimeItem.Add("meetingdateTimeItemUnavailable", true);
                        }
                        else
                        {
                            ncTimeItem.Add("meetingdateTimeItemUnavailable", time.Value<bool>("meetingdateTimeItemUnavailable", fallback: Fallback.ToDefaultValue, defaultValue: false));
                        }

                        ncTimeItem.Add("key", Guid.NewGuid().ToString());
                        ncTimeItem.Add("ncContentTypeAlias", time.ContentType.Alias);
                        ncTimeItem.Add("meetingdateTimeItem", time.Value<string>("meetingdateTimeItem", fallback: Fallback.ToDefaultValue, defaultValue: null));
                        ncTimeItems.Add(ncTimeItem);
                    }

                    ncDateItems.Add(ncDateItem);
                }

                ncItems.Add(ncDateItems);

                var ncItemString = Newtonsoft.Json.JsonConvert.SerializeObject(ncItems);
                mainpage.SetValue("meetingDatesAvailable", ncItemString);
                contentService.SaveAndPublish(mainpage);
                return new { saved = ncItemString };
            }

I am really uncertain how to structure the list correctly.
