Twitter bootstrap menu issue in device

Twitter bootstrap menu issue in device:

I was unable to select menu item by Tapping. I applied below script and it worked.

Add below script at the end of  "bootstrap-dropdown.js" file:

$('body').on('touchstart.dropdown', '.dropdown-menu', function (e) { e.stopPropagation(); });

$('.dropdown-toggle').click(function (e) {

    e.preventDefault();

    setTimeout($.proxy(function () {

        if ('ontouchstart' in document.documentElement) {

            $(this).siblings('.dropdown-backdrop').off().remove();

        }

    }, this), 0);

});
