Correct view is not rendered - Rails 4 - ruby-on-rails-4

Question

I'm trying to create a dropzone where users can drop multiple files at once. The problem is that it only renders the dropzone when I reload the webpage, and not when I open it for the first time. I mean, when I click to open the view that takes care of the uploads, I just get the browse and upload buttons that you'll see in my code, but when I reload the page I get the dropzone box. I can not see what I missing here. The code I wrote was:
_new.html.erb
<center>
<% #upload = Upload.new %>
<%= form_for #upload , html: { :multipart => true, class: "dropzone"} do |u| %>
<div class="fallback">
<%= u.file_field :file %><br>
<%= u.submit "Upload" %>
</div>
<% end %>
uploads.js.coffee
$(document).ready () ->
Dropzone.autoDiscover = false;
$("#new_upload").dropzone({
maxFilesize: 25,
paramName: "upload[file]",
addRemoveLinks: true
});
uploads_controller.rb
class UploadsController < ApplicationController
def new
#upload = Upload.new
end
def create
#upload = Upload.create(upload_params)
if #upload.save
render json: { message: "success" }, :status => 200
else
render json: { error: #upload.errors.full_messages.join(',')}, :status => 400
end
end
def destroy
#upload = Upload.find(params[:id])
if #upload.destroy
render json: { message: "Archivo eliminado." }
else
render json: { message: #upload.errors.full_messages.join(',') }
end
end
private
def upload_params
user = current_user.id
params.require(:upload).permit(:file,:user)
end
end
You could also notice that in the _new.html.erb file I'm redefining the #upload class variable, that was already defined in the controller. If I remove it the new action won't work. What's the problem there?
Please ask me if you need me to provide more code or details.
Thanks in advanced.

You should add 'data-no-turbolink': true to the link that opens that page. Turbolinks doesn't always play nice with $(document).ready so this will call the link without turbo links.
There is also a gem called jquery-turbolinks that might make the current version work without data-no-turbolink
