ActiveAdmin Autocomplete dropdown select not working

I am using activeadmin 0.4.4 along with rails3-jquery-autocomplete 1.0.15.

I was able to add autocomplete to a field.The dropdown shows perfectly as required.

However I am not able to select a value from the dropdown. (If I manually write the value in the text field it works fine). I get this error in the browser console and I am unable to figure out on how to proceed with this:

Uncaught TypeError: undefined is not a function
t.railsAutocomplete.fn.extend.init.t.autocomplete.select  -- active_adimn.js line 13982

Please suggest.
