Vaadin + Phonegap (No touchkit)

I have a Vaadin desktop application that I want to install as a native mobile app using phonegap (Phonegap build) (Embeeded as an iFrame). Everything works fine, but the moment it make a call to a phonegap plugin (Ex: sound), the application kind of freezed. Every request after this (userr click, etc) doesn’t even get to the server, but if I turn the device Off/On, the request is fulfilled and does what its needs to do, until the user makes the next action.

Is there something I’m missing?
