haml generated javascript

Hi guys,
I'm a little stumped on how to get the output from a HAML generated
list "= render :text => @providers.map(&:name)" called by the
application.js
$(document).ready( function(){
  $( '#user_provider_name' ).autocomplete({
    url: '/providers.js'
    });
});

into listed format ie.
test_01
test_02
test_03

currently the output is:
["test_02", "test_01", "test_03",
"test"]
which is shown as one string in the drop down box under the text
field ..

it seems to me the the autocomplete isn't getting the data thus the
lack of format

my devbox is running
  ruby:
    interpreter: "ruby"
    version: "1.9.2dev"
    date: "2010-07-11"
    platform: "i686-linux"
    patchlevel: "2010-07-11 revision 28618"
    full_version: "ruby 1.9.2dev (2010-07-11 revision 28618) [i686-
linux]"
