I'm trying to add themed text to an input field as shown here (under 'Prepended and appended inputs'): http://getbootstrap.com/2.3.2/base-css.html#forms

form.inc includes the bootstrap_bootstrap_append_element() function which seems to serve to add the needed css classes and spans to fields that have suffixes or prefixes. However, it's just not rendering in my node edit form.

Can anyone confirm this working for them?
