Mootools; Click Event; Ipad; Some work and Some don't

http://jsfiddle.net/styks1987/jnFKC/3/

When using the Ipad some of my 'clickable' elements work and some do not.

The code that I have provided works on desktop safari and firefox. When I try to click/touch these with the ipad, I get nothing.

Your开发者_Python百科 help is greatly appreciated. This is an excerpt from a larger project. Other elements on the same page work fine with the Ipad.

thanks,
