I am no OO expert, but I think the way that you have described it is good. So long as you are explicitely passing in your components, I think calling methods on those components is the right way to go.
Certainly this is preferable to any solution dependent upon inheritence (unless you really have an IS-A relationship - which I don't see in your example).
