Triggering Sencha Touch microloader with a custom event

// (e.g. if you need to load a certain package or framework before sencha's microloader)
// in index.html:
        <script type="text/javascript">
            window.Ext = {blinkTrigger: 'deviceready'};
        </script>
        <script type="text/javascript" src="cordova.js"></script>

        <!-- The line below must be kept intact for Sencha Command to build your application -->
        <script id="microloader" type="text/javascript" src=".sencha/app/microloader/development.js"></script>

// in .sencha\app\microloader\testing.js:

    Ext.blink = function(options) {
        if (Ext.blinkTrigger) global.document.addEventListener(Ext.blinkTrigger,function(){
            Ext.blink2(options);
        },false);
        else return Ext.blink2(options);
    }

    // rename original blink() method
    Ext.blink2 = function(options) {
    .
    .
    .
    }

// in case of pre-loading cordova, additionally override Ext.onDocumentReady():
    // . . .
    if ((Ext.browser.is.WebWorks /*|| Ext.browser.is.PhoneGap */) && !Ext.os.is.Desktop) {
        if (!Ext.readyListenerAttached) {
            Ext.readyListenerAttached = true;
            document.addEventListener(Ext.browser.is.PhoneGap ? "deviceready" : "webworksready", b, false)
        }
    } else {
