Pass parameters with EventEmitter

@Output() stopSort = new EventEmitter();

EventEmitter supports one argument, which is passed as $event to your event handler.

Wrap your parameters in an event object when you pass it to emit:

this.stopSort.emit({ event:event, ui: ui });

Then, when you handle the event, use $event:

stopSort($event) { 
  alert('event param from Component: ' +$event.event);
  alert('ui param from Component: ' + $event.ui);
}
