How to add a balloon when adding objects to the map that fall into the scope?

Question

API

Is there any code that adds objects to the map that fall into the scope?

var objects = ymaps.geoQuery(coords.map(function(p){return {coordinates:p, type: 'Point'}}));

                            objects.searchInside(myMap).addToMap(myMap);

                            myMap.events.add('boundschange', function () {
                                var visibleObjects = objects.searchInside(myMap).addToMap(myMap);
                                objects.remove(visibleObjects).removeFromMap(myMap);
                            });

I can't put a balloon on every label. I try even the simplest code from the documentation,

var placemark = new YMaps.Placemark(new YMaps.GeoPoint(37.64, 55.76));
placemark.name = "Имя метки";
placemark.description = "Описание метки";
map.addOverlay(placemark);

but it doesn't work :(((

I decided, I throw the working code

var obj = {
                                type: 'FeatureCollection',
                                    features: coords.map(function(p){
                                        return {
                                            type: 'Feature',
                                            properties: {
                                                balloonContent:  p[2]
                                            },
                                            geometry: {
                                                type: 'Point',
                                                coordinates: [p[0], p[1]]
                                            }
                                        }
                                    })
                            };


                            var objects = ymaps.geoQuery(obj);

                            objects.searchInside(myMap).addToMap(myMap);

                            myMap.events.add('boundschange', function () {
                                var visibleObjects = objects.searchInside(myMap).addToMap(myMap);
                                objects.remove(visibleObjects).removeFromMap(myMap);
                            });
