Answer 1

Even without being familiar with Socket.io, I can say that every time you instantiate a controller, you subscribe to an event.
Who will unsubscribe? Or do you think that he will somehow magically unsubscribe to you when the controller is removed?

function onGetOne() {
}

socket.on('tickets:getOne:success', onGetOne);

$scope.$on('$destroy', function() {
  socket.removeListener('tickets:getOne:success', onGetOne);
});

Answer 2

Socket work should be encapsulated in a separate service with a higher abstraction for controllers, directives, and other services.
