Rails - Jun 2010 - Element.insert_html is not function

Hi

I have created the application by following the railcast video

http://railscasts.com/episodes/74-complex-forms-part-2

However I am getting this error when I click "add element"

 RJS error:

 TypeError: Element.insert is not a function

 and then

 Element.insert("docs", { bottom: "<div
class=\"doc\">\n\n
 Doc: <input .....etc

I have added the <%= javascript_include_tag :defaults %>  in layout
files also

here is my rjs line
<%= render :partial => ''task'', :collection =>
@project.tasks %>

please help me in this regards.

new.html.erb

Plaese verify the file...


#Projects/new.html.erb

<% form_for :project, :url => projects_path do |f| %>

  <p>
    Name: <%= f.text_field :name %>
  </p>

  <div id="tasks">
    <%= render :partial => ''task'', :collection =>
@project.tasks %>
  </div>


  <%= link_to_function "Add a Task" do |page|

    page.insert_html:bottom, :tasks,  :partial => ''task'',
:object =>
Task.new
  end %>

  <p><%= submit_tag "Create Project" %></p>
<% end %>




#My controller i.e projects

class ProjectsController < ApplicationController

def index
@projects = Project.find(:all)
end


def new
  @project = Project.new
 @project.tasks.build

end

def create
  @project = Project.new(params[:project])
  if @project.save
    flash[:notice] = "Successfully created project and tasks."
    redirect_to projects_path
  else
    render :action => ''new''
  end
end

def edit
  @project = Project.find(params[:id])
end

def update
  params[:project][:existing_task_attributes] ||= {}

  @project = Project.find(params[:id])
  if @project.update_attributes(params[:project])
