onFinish is not working in ionRangeSlider

Can you please provide the what is the bug in the following code

$("#my_slide").ionRangeSlider({
    type: "double",
    min: 1000,
    max: 12000,
    step: 500,
    force_edges: true,
    onFinish:function () {
        alert('slider drag finished');
        }     
});

There is no alert after finishing the click and drag on slider.

@valtido, it was the recent change to slider core, which i will probably revert soon, because it is really confusing.

You may have some local JS-issues, open web developer console and look for errors. Remember, if you are using some other code, alert function could be changed in it and will do nothing, like this: http://jsfiddle.net/278ktdnz/1/
