fun Disposable.disposeOnDestroy(lifecycleOwner: LifecycleOwner) {
    lifecycleOwner.lifecycle.addObserver(object : DefaultLifecycleObserver {
        override fun onDestroy(owner: LifecycleOwner) {
            [e-mail]()
        }
    })
}

// usage
updateBasicInfo().subscribe() {
   //...
   onSubscribe {
      it.attachToLifecycle(viewLifecycleOwner)
   }
}

I wrote this extension for disposing subscriptions. I know it might seems stupid but my actual concern is object leak.
updateBasicInfo creates a new observable and it call an web API.
does DefaultLifecycleObserver keep the Disposable (observable) reference, even when the observable has been completed?
