(2.1.0) Not works on mobile IE10

I returned back to the 1.3.0 version because 2.1.0 not works.
Even the demo "/test/function/public/index.html" not view retina images (with the correct path to the retina.min.js file).

I've missed to insert this script code:
retinajs();
Now it works but on App of Windows Phone not view the images with high resolution.
Maybe there's a bug in the mobile IE10.

For other situations I've used this code but with retinajs not works:
window.devicePixelRatio = window.devicePixelRatio || window.screen.deviceXDPI / window.screen.logicalXDPI;
