Rails 3.1 javascript file usage

Question

I have a rails 3.1 app where I can create mail blasts. I have a list of all my blasts with a mail link to mail a specific blast (using ajax). I have a custom action in my blasts controller that I want to use. When I click the link it wants to call show.js.coffee instead of mail.js.coffee for ex. how do I force it to use the action I created. Everything works when I put everything in the show action of my controller and show.js.coffee but not the mail action and mail.js.coffee etc.

This is my blast partial

<td><% if can? :create, Blast%><%= link_to "Mail",blast,:action => :mail  :confirm => "Are you sure?",:remote => true%><%end%></td>

This is the method in controller

def mail
  @customers = Customer.all
  @mailcustomers = Customer.where(:opted_out => false)
  @blast = Blast.find(params[:id])
end

This is in my mail.js.coffee file

 <% @mailcustomers.each do |f|%>
   <% BlastMailer.mail_blast(f,@blast).deliver %>
 <%end%>

In routes.rb

resources :blasts do
  collection {  post :mail  }
end

Answer 1

I figured out what I needed to do. This is the line that worked.

<td>
  <% if can? :create, Blast%>
    <%= link_to "Mail", {:action => :mail, :id=>blast.id}, :method => :post,:confirm => "Are you sure?",:remote => true%>
  <%end%>
</td>
