attempting to trigger C# event with MultiSortablelistGroup

[AndyWatkins]

Hi Alex,

I learning Blazor and C#. Im an old VB desktop guy.
I am having some problems understanding how to capture a list Item and triggering an event when moving an item from one list to another. The UI works beautifully. My problem arises when an Item is moved, I need to trigger an event in the @code block. The event needs the item being changed.
I have attempted to implement "onRemove" and it seems to trigger the custom event in the browser but the code never receives the event.
