Event bubbling doesn't bubble all the way to the document level on iOS. Here is one way to make that happen.

ios_event.coffee

touchPointer: ->
      document.documentElement.style.cursor = "pointer"
      
# Call this on init
if Modernizr.touch
        document.addEventListener "touchstart", touchPointer()

Here is some linkage to back this up.

On iOS the "click" event does not bubble up to the document with an exception of inputs and links, it stops right before the body.
Apparently setting the documentElement cursor to pointer fixes this.

From the jQuery .live documentation

On mobile iOS (iPhone, iPad and iPod Touch) the click event does not bubble to the document body for most elements and cannot be used with .live() without applying one of the following workarounds:

• Use natively clickable elements such as a or button, as both of these do bubble to document.
• Use .on() or .delegate() attached to an element below the level of document.body, since mobile iOS does bubble within the body.
• Apply the CSS style cursor:pointer to the element that needs to bubble clicks (or a parent including document.documentElement).
  Note however, this will disable copy\paste on the element and cause it to be highlighted when touched.
