two instants of loader

I use it on angular js and create class to manage it

 var clsLoader = (function () {
        var mprogress = new Mprogress({
            template: 2
        });
        return {
            show: function () {
                mprogress.start();
            },
            hide: function () {
                mprogress.end();
            }
        }
    })();

when i have two call for function show, and two call for function hide the loader not ended?

same issue here.

I definitely want this as well. I can't use this plugin without it.
