link_to :confirm displays popup twice

Question

This tag with rails 3

<%= link_to \'Destroy\', item, :method => :delete,:confirm=>\'Are you sure?\' %>

produces this html

Answer 1

In my case (Rails 3.2.13), I had to delete rails.js to fix the same problem.

I did not explicitly reference rails.js, nor did changing config.assets.debug help.
