If using jQuery Mobile you will experience the new window when using the data-ajax=’false’ attribute. In fact, this will happen whenever ajaxEnabled is turned off, being by and external link, by a $.mobile.ajaxEnabled setting or by having a target=”” attribute.

You may fix it using this:

$("a[data-ajax='false']").live("click", function(event){
  if (this.href) {
    event.preventDefault();
    location.href=this.href;
    return false;
  }
});

(Thanks to Richard Poole for the live() method – wasn’t working with bind())

If you’ve turned ajaxEnabled off globally, you will need to drop the [data-ajax=’false’].

This took me rather long to figure out as I was expecting it to be a jQuery Mobile specific problem where in fact it was the Ajax linking that actually prohibited the new window.
