That's too much work.  How about googling "dojo autocomplete", and
reading an article like this:

http://today.java.net/pub/a/today/2006/04/27/building-ajax-with-dojo-and-json.html

To make that work with Catalyst, just replace the java:

   public String toJSONString() throws JSONException {
    JSONObject jsonObj = new JSONObject();
    jsonObj.put("bookId", new Integer(this.bookId));
    jsonObj.put("title", this.title);
    jsonObj.put("isbn", this.isbn);
    jsonObj.put("author", this.author);
    return jsonObj.toString();
   }

With Perl:

   sub search_for_book :Local {
      my ($self, $c, $search_term) = @_;
      my @results = $c->model('Books')->search_for_completion_of($search_term);
      $c->stash->{json} = { results => \@results };
      $c->detach($c->view('JSON'));
      # or whatever
   } 

Catalyst rarely cares what you use for javascript.  You send the
javascript code data, the javascript does its thing, and perhaps the
javascript requests some more data.  The hard part is javascript, so
that's what you need to learn first.
