We have a custom implementation to avoid doble submissions which causes some custom problems 😌 This commit should fix the following three specs spec/features/comments/legislation_annotations_spec.rb:367 spec/features/comments/legislation_questions_spec.rb:333 spec/features/custom/probe_option_comments_spec.rb:298 One of the custom problems comes from ajax:success[1] not being triggered, instead only ajax:complete seems to be triggered We should remove this custom implementation and use the standard solution provided in rails[2] [1] https://github.com/AyuntamientoMadrid/consul/blob/master/app/assets/java scripts/prevent_double_submission.js.coffee#L28 [2] https://stackoverflow.com/questions/9570912/how-to-disable-a-form-submit -button-a-l%C3%A0-ruby-on-rails-way/9572893#9572893
