I tried it again with a global and local function, with this repro. Either of those works just not this.onDeviceReady. Also if I refer to the variable 'this' was assigned to instead of 'this', it works. Thus it seems it is a scoping issue of 'this' when the function is applied.

Repro on iOS 6:
1. Load app
2. Click on Yahoo Remote URL button
3. Click on Home transparent button

{code}
       bindEvents: function() {
        // global works for CB-2094
        x = function() {
            alert('deviceready global');
        }
        document.addEventListener('deviceready', x, false);
        // local works for CB-2094
        var y = function() {
            alert('deviceready global');
        }
        document.addEventListener('deviceready', y, false);
        // local works for CB-2094
        function z() {
            alert('deviceready global');
        }
        document.addEventListener('deviceready', z, false);
        // this WORKS for CB-2094
        document.addEventListener('deviceready', app.onDeviceReady, false);
        // this does NOT work for CB-2094
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
{code}

> I've added a semi transparent home button to the MainViewController which loads the local index.html file within my Cordova 2.30 project. After I've moved on to a remote page, (may be Cordova enabled, may not) and I return with the home button, sometimes deviceready does not fire. It may fire a few times then stop. Once it stops the only way to fix the issue is to send the app to the background (deviceready will now fire) and return.
> This same technique works fine in Cordova 2.20
