Currently working on a project where the client can add new agenda items to the agenda. When the client adds a new item they must choose a date and time. What i want is to sort on this client made date and time on the "Agenda" page. What is the best way to create this? Currently i'm sorting on the CreatedDate but as you can imagine this is not a good solution.

Current code for Agenda.cshtml

@using umbraco.BusinessLogic;
@using umbraco.cms.businesslogic.web;
@{var numberOfItems = 3;}

@foreach(var item in @Model.Children.Where("umbracoNaviHide != true").Take(numberOfItems)){
      
       
        <div class="newBand">                                                                                                      
             <p class="bandTitle">@item.title</p>            
             <img src="@item.foto" width="200" class="alignright"/><div class="bandTekst">@item.text Aanvang: <b>@item.dateAndTime</b></div>
        </div>
          
}
