according to http://www.mylearning.in/2015/06/close-modal-pop-up-on-back-button.html

    $('#myModal').on('show.bs.modal', function(e) {
        window.location.hash = "modal";
    });

    $(window).on('hashchange', function (event) {
        if(window.location.hash != "#modal") {
            $('#myModal').modal('hide');
        }
    });
