Ironically i would like some feed back on a Stack level too deep error!

I’ve been looking through my code for hours and can’t figure out what’s wrong!
It occurs when I try to load a javascript-file that is located in the welcome folder, and this is how the code looks like this:

application.html.erb:

<!DOCTYPE html>
<html>
<head>
  <title>Project1</title>
  <%= stylesheet_link_tag "application" %>
  <%= javascript_include_tag "application" %>
  <%= csrf_meta_tags %>

</head>
<body>

<%= yield %>
</body>
</html>

index.html.erb:

<!DOCTYPE html>
<div id="wrapper">
  <div id="header" >
    <div id="Lorem">
      <b>Lorem
    </div>
    <div id="Ipsum">
      <b><p>Ipsum</p>
    </div>
  </div>
  <div id="menuwrapper">
    <div class="tabArea">
      <%= link_to 'Link', {:action => 'update', :controller => 'welcome'},{:class=>"tab",:remote=>true} %>
    </div>
  </div>
  <div id="wrapper2">
  </div>
</div>

welcome_controller.rb:

#coding:utf-8
class WelcomeController < ApplicationController  
  def index

  end
  def update
    respond_to do |format| format.js { render :update => update} end
  end
end

update.js.erb:

$(alert("Hello"));

routes.rb:

  get "welcome/index"
  get "welcome/update"

Eternally grateful for any ideas of whats causing the overflow! Thanks you.

    Per comments earlier,

    Rails is being told to render the update action when rendering for JS format on the update action. The offending code is:

    {render :update => update}
