Have you found a solution to this? I am having this issue currently.
Having issue with Rails 5 and Turbolinks. I have added the jquery-turbolinks gem and still having issues.
//= require jquery
//= require jquery.turbolinks
//= require jquery_ujs
//= require tether
//= require bootstrap-sprockets
//= require bootstrap-datepicker/core
//= require_tree .
//= require turbolinks
