minChars 0 doesn't detect change on input

[edraobdu]

Hi.
When minChars is 0, by focus on the input it shows all the options, but, by clicking on any option the event "change" of the input doesn't work. It works only if I type for searching, but not at the first time when it shows all the options.

Using the demo:

$('#hero-demo').autoComplete({
                minChars: 0,
                source: function(term, suggest){
                    term = term.toLowerCase();
                    var choices = ['ActionScript', 'AppleScript', 'Asp', 'Assembly', 'BASIC', 'Batch', 'C', 'C++', 'CSS', 'Clojure', 'COBOL', 'ColdFusion', 'Erlang', 'Fortran', 'Groovy', 'Haskell', 'HTML', 'Java', 'JavaScript', 'Lisp', 'Perl', 'PHP', 'PowerShell', 'Python', 'Ruby', 'Scala', 'Scheme', 'SQL', 'TeX', 'XML'];
                    var suggestions = [];
                    for (i=0;i<choices.length;i++)
                        if (~choices[i].toLowerCase().indexOf(term)) suggestions.push(choices[i]);
                    suggest(suggestions);
                }
            }).on('change', function(){
    window.alert('hey Apple');
});

I'd appreciate any help, thanks!
