Event handlers cannot be overwritten - With react

Hi,

I'm using your youtube-player with react and I pleased of how it work but I have a problem when I want to destroy and recreate a player.

If you don't know how react work there is the event componentDidMount and componentWillUnmount that are called when the component is created and destroyed.

At componentWillUnmount I create the player and bind one event. When componentWillUnmount is launch (changing page for example) I unbind the player event. But when I create again the player (componentWillUnmount ) I got this error :

Event handlers cannot be overwritten

Is there something else I should do when I when to delete the player ?
