Запись текста из массива в iconContent и balloonHeader

ymaps.ready(function () {
var myMap = new ymaps.Map('map',{
    center: [46.953344, 142.741549],
    controls:['zoomControl','geolocationControl'],
    zoom : 16
});

Создание макета балуна на основе Twitter Bootstrap.

MyBalloonLayout = ymaps.templateLayoutFactory.createClass(
    '<div class="popover top">' +

            this.applyElementOffset();
            this._$element.find('.close')

        onCloseClick: function (e) {
            e.preventDefault();

        getShape: function () {

            position = this._$element.position();
            return new ymaps.shape.Rectangle(new ymaps.geometry.pixel.Rectangle([

MyBalloonContentLayout = ymaps.templateLayoutFactory.createClass(
    '<h3 class="popover-title">$[properties.balloonHeader]</h3>' +

Кластеризация:

clusterer = new ymaps.Clusterer({
    clusterIconLayout: 'default#pieChart',
    clusterIconPieChartRadius: 1.5 * myMap.getZoom()+5,
    clusterIconPieChartCoreRadius: 10,
    clusterIconPieChartStrokeWidth: 3,
    groupByCoordinates: false,
    hasBalloon: false,
    hasHint: false,
    gridSize:512,
    maxZoom:18,
    clusterDisableClickZoom: false
 });

    getPointData = function () {
    return {
        iconContent: ['<div  align="center" ><input id="slider" type="submit" 
class="block2" value="Адрес" /></div>',],
        balloonHeader: ['<div id="slider2" class="header">Адрес</div>'],
        balloonContent: ['<div  align="center"><input id="slider3" 
type="button" onclick="smena(0)" class="block1" value="ОТКРЫТЬ""></div>',],
    };
};
 getPointOptions = function () {
        return {
            iconLayout: 'default#imageWithContent',
            iconShape: {
                type: 'Rectangle',
                coordinates: [
                    [-20, -50], [50, 20]
                ]
            },
            iconColor: '#930005',
            iconImageHref: 'locked.png',
            iconImageOffset: [-20, -50],
            iconImageSize: [3.5 * myMap.getZoom() + 8, 3.5 * myMap.getZoom() 
  + 8],
            balloonLayout: MyBalloonLayout,
            balloonContentLayout: MyBalloonContentLayout,
            balloonPanelMaxMapArea: 0,
            iconContentOffset: [-50, 120]
        };
    };
    points = [
        [46.950306, 142.756225], [46.956177, 142.742292]
    ];
    addressP = [
        "Ленин", "Сталин"
    ];
 geoObjects = [];
 for (var i = 0, len = points.length; i < len; i++) {
    geoObjects[i] = new ymaps.Placemark(points[i], getPointData(i), 
getPointOptions(i));
};
clusterer.add(geoObjects);
myMap.geoObjects.add(clusterer);

и функция, которая должна менять иконку метки

function smena(i) {
    geoObjects[i].options.set({iconImageHref: 'locked1.png', iconColor: '#00bf0d',});
}

Вопроса два:

1. Как записать значения из массива addressP в подпись метки и шапку балуна.
2. Как передать в функцию smena номер метки, чтобы именно она меняла иконку метки?
