evalJS's javascript need try/catch.

Sometimes, There's no cordova object on html files. But, unfortunately CVViewController calls some notification using notification center and call evalJS using these method. (cordova.fireDocumentEvent('resign'), cordova.fireDocumentEvent('resume'), cordova.fireDocumentEvent('active'), cordova.fireDocumentEvent('pause')).
But evalJS's javascript starts with cordova.require. So, at that time there's no cordova object? Show's big alert view.
Need try/catch for this.
