Lignhtning fast autocompleter IE issue

Hi friends,
I was using the rails recipes for the feature called Lightning fast auto
completer where we search and save the contents to be displayed in the
JavaScript Array .

something like in some .js file
var authors = new Array(<%= @authors.size %>);
<% @authors.each_with_index do |author, index| %>
authors[<%= index %>] = “<%= %>”;
<% end %>

and do this in the head section the rhtml file

<%= javascript_include_tag :defaults %>

and in the controller
def authors_for_lookup
@authors = Author.find(:all)
@headers[’ content-type’ ] = ’ text/javascript’
