Code of my app where scriptProcessor Node is not working on iOS

I have created an app in HTML 5 that generates white noise on its own using a ScriptProcessorNode (Google Chrome) or a JavaScriptNode (Safari).
All is working fine for Google Chrome/Safari on my Mac and also in my Android phone but it is not working in Safari/Chrome on my iPod Touch 5th/iPad 4th on iOS 6.1.2. 

Browsers checked:

iOS:
Mob Safari 6.0 (Not working) (536.26 WebKit)
Chrome Mob iOS 30.0.1.1599 (Not working) (536.26 WebKit)
Mob Safari 7.0 (Not working)

MAC:
Desktop Chrome 30.0.1599 on MAC (Working) (537.36 WebKit)
Desktop Safari 6.0.5 on Mac (Working) (536.30.1 WebKit)

Android: 

Chrome 29.0.1547.59 1547059 (Working) (WebKit 537.36)

I have a button on the screen that when it is touched the gainNode is connected to context.destination or it's disconnected. I can see that onaudioprocess event is not triggered on my iPod (iOS 6.1.2 Safari and Chrome)...

I am attaching the code of my simple app.

What am I doing wrong? Is something different from Safari/Chrome on iOS than for MAC that I am not considering?

I need to create sound samples on the fly... If this work I would add a filter node to filter the white noise for generating other sounds as the user wants.

Thanks!
