add-to-list works fine for me, like this: (taken straight of my emacs.org
file)
#+BEGIN_SRC emacs-lisp
 (add-to-list 'org-capture-templates '("J" "log job or activity to date
tree for UE application"
                                         (file+datetree "~/Dropbox/orgzly/
jobs.org")
                                       "* %^{Company or activity} %^{Job}
  - Direct Contact:%^{y/n}
  - Resume submitted:%^{y/n}
  - Result:%^{[h]ired/[n]ot hired/[i]nterview}
  %?"
  :prepend t :immediate-finish)
  )
#+END_SRC
