Trying to remove focus from email or password Text Fields when user taps outside of them but can't target the Text Fields via id from the controller. i.e. $.email.blur();

That's because $ refers to the listview.js controller and since the template is repeated for every item in the list, it cannot refer to it.

Just take a look at the generated code in the Resources folder and see if there is a way to get to it.
