Text insertion cursor (caret) appears above other elements in mobile browser

OK, not sure what has happened with the fiddle, but this one works: http://jsfiddle.net/XQf8N/33/

This is the same, except instead of manually listening for the events and then calling blur() on the textbox, the blur() is fired from a knockout binding.

As I am using knockout, I may as well blur the textbox in the knockout event binding instead.
