Strange bootstrap behavior with Chrome/Sierra

I’m under OSX Sierra, Chrome 57, Bootstrap 3.3.7, Font awesome 4.

The following :

<button type="button" class="btn btn-primary btn-md" data-loading-text="<i class='fa fa-circle-o-notch fa-spin'></i> wait">Go</button>

And the Js part :

$('.btn').on("click", (evt) => {
  $('.btn').button("loading");
});

Does not work correctly. But It works with Safari !?

Any idea or workaround ?
