You either should use this.Property = newobject(...) -- but you can only do this for custom classes and they will not be "added to the form"

or

Remove the original container first and create a new container.

Use RemoveObject method first and then re-add the new container using the same name.

In other words, you will be re-using the same name for the new object (and not an object property).
