ReadMe example Doesn't Work

[dbareis]

"https://github.com/axenox/onscan.js/blob/master/README.md" says

// Register event listener
document.addEventListener('scan', function(sScancode, iQuantity) {
    alert(iQuantity + 'x ' + sScancode); 
});

That doesn't work, this does:

document.addEventListener('scan', function(cEvent) {
    //alert(iQuantity + 'x ' + sScancode);
    alert(cEvent.detail.qty + 'x ' + cEvent.detail.scanCode);
});
