Not sure what I'm doing wrong here, have managed to turn my issue into a simple example of what is going wrong at:

Basically I'm trying to get it so that when a modal closes the hidden.bs.modal event sends the focus back to an input box on the page. I'm sure I've had this working before but cannot work out where I have gone wrong.

If I tell the hidden event to instead just put a value into the input box it shows up, I just can't get it to focus, I'm thinking it's a timing issue but then that's why I'm using the 'hidden' event as opposed to the 'hide' event.
