bindBind this handler to the given component. This method is called by the host component immediately after this behavior is added to it. This method is useful if you need to do initialization based on the component it is attached and you can't wait to do it at render time. Keep in mind that if you decide to keep a reference to the host component, it is not thread safe anymore, and should thus only be used in situations where you do not reuse the behavior for multiple components.
