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

I've been used to include the javascript_include_tag at the bottom of my haml-layout-file.

With Rails4 and Turbolinks it happens that:

• Everything ok on the first load of a page (popup for confirmation appears only once)
• Visiting another page -> popup occurs twice
• Visiting one more page -> popup occurs three times
• and so on
• until I reload the page.

I solved the problem by moving the javascript_include_tag from the bottom into
