How to add confirm message with link

i wanted add confirmation message on link_to function ruby.

= link_to 'reset message', :action=>'reset' ,:confirm=>'are sure?'

any ideas why it's not working?

first, should verify layout have jquery_ujs. best practice including in main application.js:

//= require jquery_ujs

check included application.js in layout:

= javascript_include_tag :application

while, in development mode, view source html , verify jquery_ujs.js exists.

run server , verify link tag has data-confirm value, example:

<a href="/articles/1" data-confirm="are sure?" data-method="delete">

if steps correct, should work!
