Hi all, 

I have autocomplete implemented like :

1.     var cbx_search_in_description= $("#cbx_search_in_description").is(':checked') ? 1 : '0'
2.     var cbx_search_in_past_events= $("#cbx_search_in_past_events").is(':checked') ? 1 : '0'
3.     $( "#autocomplete_events" ).autocomplete({
4.         source: function( request, response ) {
5.             $.ajax({
6.                 url: ajax_object.backend_ajaxurl,
7.                 dataType: "json",
8.                 data: {
9.                     action: 'autocomplete-events',
10.                     artist_id: this_m_artist_id,
11.                     search_in_description : cbx_search_in_description,
12.                     search_in_past_events : cbx_search_in_past_events,
13.                     q: request.term
14.                 },
15.                 success: function( data ) {
16.                     response( $.map( data, function( item ) {
17.                         return {
18.                             value: item.lat+"="+item.lng,
19.                             label: item.place_name
20.                         }
21.                     }));
22.                 }
23.             });
24.         },

It works and question is, that I want to make autocomplete with some additive parameters ( cbx_search_in_description and cbx_search_in_past_events )

and I want to trigger autocomplete event when I click on these 2 checkboxes.

I tried on onchange event to run method 

1. $( "#autocomplete_events" ).change();

but it does not work. How to make correctly?
