Google Map marker listener not work

Hi guys,
I am trying to make my own map marker clickable and do some action then. I have this code:

let map_place = new MapPlace();
 map_place.location = location; = point;
        map_place.marker = new google.maps.Marker({
            position: location,
            icon: iconType,
            opacity: 0.4,
        let self = this;
        let info = new google.maps.InfoWindow();
        google.maps.event.addListener(map_place.marker, 'click', () => {
          console.log("MARKER CLICK")

Markers are shown correctly in the map. But no action when I click some of them. What is wrong on my implementation?


EDIT: Even implementation by google documentation do nothing:

map_place.marker.addListener('click', function () {
           console.log("CLICK MARKER")
