Rails 4: Partial can't use javascript after being rendered (with ajax)

I'm doing an Ajax request with CoffeeScript and then rendering a partial from my controller, but then after that the partial has been rendered it can't use the Javascript I had previously.

Example:

At the end my action of my home_controller I have: 

respond_to do |format|
   format.html { render partial: 'frame' }
end

In my home.js.coffee: 

$('#plouf').click -> 
  alert('test')

Then in my partial _frame.html.erb (in the home folder of the views folder)

<span id="plouf">test<span>

If I click on this span, nothing happens... 

<%= javascript_include_tag "application", "data-turbolinks-track" => true %>

But if I add this line in my partial it works, but I know it's ugly since I already did it in my application.html.erb

Am I missing something, or is it normal that partial can't use any previous Javascript?

Partials are compiled into the view before javascript is run by the browser.

What you need is

$(document).on 'click', '#plouf', ->
  alert('test')

This binds the event to the document, so when turbolinks or ajax reloads the HTML, your event handler is still active.
