$( "#foo" ).on( "custom", function( event, param1, param2 ) {

$('body').trigger('this_works', [{data: [1, 2, 3]}, 'something']);

$('body').on('this_works', function (event, json, string) {
  // parameter is stocked in json.data here.
  console.log(event, json, string);
});// There are quite a few abstracted versions of the following
$('element').on('event', function() {
	// Do something
});

// Where 'event' is something such as 'click', 'hover' etc

// They are abstracted as seen below
$('element').click(function(){
	// Do something
});
$('element').hover(function(){
	// Do something
});

// etc...$( "#foo" ).trigger( "click" );
