Subscribe MEF IWpfTextViewCreationListener events in VsPackage

Hello,

It might be a dumb question but haunting me for long a time.

I wish to handle the events like CarePositionChanged event in my VsPackage. DTE.Events also have LineChanged event but I want caret position change event which is there only IWpfTextViewCreationListener.

Would anybody please suggest the correct  way to do it.

Thanks
