Blazor webassembly, state management. Refresh child components

Question

I am selecting items from the list, and displaying their different content. It is working correctly with this code:

public class ItemState
{
    public Item CurrentItem { get; set; }
    public event Action OnItemSelected;
    public void SetItemValue(Item item)
    {
        CurrentItem = item;
        NotifyStateChanged();
    }

    private void NotifyStateChanged() => OnItemSelected?.Invoke();
}

protected override void OnInitialized()
{
    ItemState.OnItemSelected += StateHasChanged;
}

In the Item component I am using other components and passing as parameter Item itself, like: <ItemHistory ItemModel="@Item"/> But ItemHIstory component is not refreshing, when selecting different items. There is always shown first selected item's history.

Where is the problem?

The answer was to use StateContainer, so properties then are are accessible for all components. https://learn.microsoft.com/en-us/aspnet/core/blazor/state-management?view=aspnetcore-5.0&pivots=webassembly
