Вот models

namespace Testing_ItemsControl.Models;

public class Crockery
{
    public string Title { get; set; }
    public int Number{ get; set; }

    public Crockery(string title, int number)
    {
        Title = title;
        Number = number;
        
    }
}

вот viewmodels

public class MainWindowViewModel : ViewModelBase
{
    public ObservableCollection<Crockery> CrockeryList { get; set; }
    public ReactiveCommand <Unit, Unit> CreateItem { get; }
        
    public MainWindowViewModel()
    {
        CrockeryList = new ObservableCollection<Crockery>(new List<Crockery>());
        
        CreateItem = ReactiveCommand.Create(() =>
        {
            CrockeryList.Add(new Crockery("sad", 22));
        });
    }
}
