How to use requireFailure in Hammer.js?

I'm not exactly sure how to set the element on which to apply my function in the Hammer.js frame. There in the API itself is passed the following syntax:

var horizontal = new Hammer.Pan({
    event: 'panh',
    direction: Hammer.DIRECTION_HORIZONTAL
});
var vertical = new Hammer.Pan({
    event: 'panv',
    direction: Hammer.DIRECTION_VERTICAL
});
vertical.requireFailure(horizontal);

I can not figure out how to apply this code to my project. I would like to have the effects on the document.getElementById('hitArea') element if this can be useful.
