Timeout sencha touch on Ipad

I am having an issue with my hybrid app on iOS, concretely I am working with Sencha Touch and the desktop version It works correctly with the specified timeout (5 min) but in the iOS version is not working properly, (after 60 seconds fires the timeout message) it hasn´t "getting" the timeout value. I don´t know the cause but I have seen this link with a similar problem.

I tried this code but it is not working...

Code:

if (Ext .os.is .iPad){ 

Code:

               setTimeout(Ext.emptyFn(),timeout); 
}
