Как привязать метод onMyLocationButtonClick () Google maps к своей кнопке?

Доброго времени суток!

Работаю с Google Maps. Все стандартные элементы управления на карте отключил. Создал свой toolbar с фильтрами маркеров по карте и хочу добавить на него кнопку "Моё местоположение". Возник вопрос: как привязать к ней стандартную onMyLocationButtonClick () ?

Сейчас создал Кастомный элемент управления

controlUI.addEventListener('click', function() {
          map.setCenter(pos);
        });

Возник еще один вопрос. Какой обобьет передать в map.setCenter?

function initMap() {

  var map = new google.maps.Map(document.getElementById('map'), {          
    disableDefaultUI: true,
    zoom: 14, styles:[{featureType:"water",elementType:"geometry.fill",stylers:[{color:"#d3d3d3"}]},{featureType:"transit",stylers:[{color:"#808080"},{visibility:"off"}]},{featureType:"road.highway",elementType:"geometry.stroke",stylers:[{visibility:"on"},{color:"#b3b3b3"}]},{featureType:"road.highway",elementType:"geometry.fill",stylers:[{color:"#ffffff"}]},{featureType:"road.local",elementType:"geometry.fill",stylers:[{visibility:"on"},{color:"#ffffff"},{weight:1.8}]},{featureType:"road.local",elementType:"geometry.stroke",stylers:[{color:"#d7d7d7"}]},{featureType:"poi",elementType:"geometry.fill",stylers:[{visibility:"on"},{color:"#ebebeb"}]},{featureType:"administrative",elementType:"geometry",stylers:[{color:"#a7a7a7"}]},{featureType:"road.arterial",elementType:"geometry.fill",stylers:[{color:"#ffffff"}]},{featureType:"road.arterial",elementType:"geometry.fill",stylers:[{color:"#ffffff"}]},{featureType:"landscape",elementType:"geometry.fill",stylers:[{visibility:"on"},{color:"#efefef"}]},{featureType:"road",elementType:"labels.text.fill",stylers:[{color:"#696969"}]},{featureType:"administrative",elementType:"labels.text.fill",stylers:[{visibility:"on"},{color:"#737373"}]},{featureType:"poi",elementType:"labels.icon",stylers:[{visibility:"off"}]},{featureType:"poi",elementType:"labels",stylers:[{visibility:"off"}]},{featureType:"road.arterial",elementType:"geometry.stroke",stylers:[{color:"#d6d6d6"}]},{featureType:"road",elementType:"labels.icon",stylers:[{visibility:"off"}]},{featureType:"poi",elementType:"geometry.fill",stylers:[{color:"#dadada"}]}]
  });

      var centerControlDiv = document.createElement('div');
      var centerControl = new CenterControl(centerControlDiv, map);

      centerControlDiv.index = 1;
      map.controls[google.maps.ControlPosition.TOP_CENTER].push(centerControlDiv);


      var infoWindow = new google.maps.InfoWindow({map: map});
      if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(function(position) {
          var pos = {
            lat: position.coords.latitude,
            lng: position.coords.longitude
          };

          infoWindow.setPosition(pos);
          infoWindow.setContent('Ты здесь, братан!');
          map.setCenter(pos);
        }, function() {
          handleLocationError(true, infoWindow, map.getCenter());
        });
      } else {
          // Browser doesn't support Geolocation
          handleLocationError(false, infoWindow, map.getCenter());
        }
      }

      function handleLocationError(browserHasGeolocation, infoWindow, pos) {
        infoWindow.setPosition(pos);
        infoWindow.setContent(browserHasGeolocation ?
          'Error: The Geolocation service failed.' :
          'Error: Your browser doesn\'t support geolocation.');
      }

        controlUI.addEventListener('click', function() {

      }

Заранее благодарен!
