Dear colleagues, could you tell me how to create components with collections among their properties?

I'm making a visual component "Oscilloscope". This component has a "Channels" property. I made these "channels" as TCollectionItem and put them in the collection. In the IDE in the component inspector, everything is displayed correctly, channels are added, removed, etc., but the properties of only the first added channels are saved! If you change the properties in an existing channel, they are visually displayed, but everything is compiled with the same, unchanged property values! And nothing changes in the form file either.

What needs to be done so that changes made in the component inspector are saved?

Thanks a lot!
I didn't implement the GetOwner function in the "channel" and that was the problem. Thanks to your advice, I fixed the error!
