Dropdown Js Doesn't Work On Ipad

Hello Chris83,

1stly would like to thanks for an awesome extension.

I just tested my app on iPad today, the dropdown (TbMenu) does not work.

When i click on the sub menu it just close, no action trigger. I look like on iPad browser it does not recognize click.

I also test on your demo web site, it does not work as well.

Any work around solution here ?
