DateTimeShortcut.js in admin, date picker not triggering 'change'..

[hagan]

Hi,

I'm not sure if this is the correct approach or not.. But i'm finding the trigger event in the DateTimeShortcut.js is not triggering changes when you click on a date. I've done something similar to the following:

admin.py

class CustomAdmin(admin.ModelAdmin):

...

    class Media:

        js = (

       'js/moment.min.js',

       'apps/core/custom_script.js',

   )

apps/core/custom_script.js

 (function($) {

     $(function () {

       $("input#id_start_date[type='text']").change(function(){

            alert("element changed");

        });

    });

})(django.jQuery);

If I modify the DateTimeShortcut.js in django source so that `django.jQuery(DateTimeShortcuts.calendarInputs[num]).trigger("change");` is called before the focus() and after DateTimeShortcuts.calendarInputs[num].value is set it works as expected. Is there an easier/better way to do this? Do i need to create a PR with the affect lines patched?

django/contrib/admin/static/admin/js/admin/DateTimeShortcut.js

...

415:    DateTimeShortcuts.calendarInputs[num].value = new Date(y, m - 1, d).strftime(format);

416:    django.jQuery(DateTimeShortcuts.calendarInputs[num]).trigger("change");  // PATCH

417:    DateTimeShortcuts.calendarInputs[num].focus();

Running Django==1.10.1

thanks!
