Create a new component

The default constructor signature of a binding component is to receive an parent component to be bound to, an optional name relative to the parent, and keyword arguments which will be placed in the new object's dictionary, to override the specified bindings.

Note that some component factories (such as binding.Component) may be more lenient than this interface requires, by allowing you to omit the parentComponent argument. But if you do not know this is true for the object you are calling, you should assume the parent component is required.
