openlayers - Looping through an array to show multiple points on the map

I am trying to add multiple points on the map. Data comes from the server as a multi array.

JSFiddle.

Notice that all points share the same name (when clicking on the point)

This is the response from PHP:

[
{
name: "Parking0001",
lat: "35.1495",

lon: "33.39243"
},
{
name: "RecycleBin0001",
lat: "35.1495",
lon: "33.39243"
},
{
name: "WaterA27",
lat: "35.1495",

lon: "33.39243"
},
{
name: "WaterA12",
lat: "35.1495",
lon: "33.39243"
}
]

Something I am doing wrong and i get undefined on iconFeature in the loop

function OpeNlayers(data) {

    var iconFeature = new ol.Feature({
        geometry: new ol.geom.Point([199, 154]),
        name: 'A point',
        population: 4000,
        rainfall: 500
    });

    var iconStyle = new ol.style.Style({

        image: new ol.style.Icon({
            anchor: [0.5, 0.5],
            anchorXUnits: 'fraction',
            anchorYUnits: 'pixels',
            src: 'icon.png'
        })
    });

    var vectorSource = new ol.source.Vector({
        features: []

    });

    var vectorLayer = new ol.layer.Vector({
        source: vectorSource
    });

    var rasterLayer = new ol.layer.Tile({
        source: new ol.source.TileJSON({
            url: 'https://a.tiles.mapbox.com/v3/aj.1x1-degrees.json',
            crossOrigin: ''

        })
    });

    $.each(data, (index, data) => {
        let iconFeature = new ol.Feature({
            geometry: new ol.geom.Point([data.lon, data.lat]).transform('EPSG:4326', 'EPSG:3857'),
            name: data.name
        })
        iconFeature.setStyle(iconStyle)
        vectorSource.addFeature(iconFeature)

    })

    var map = new ol.Map({
        target: 'map',
        layers: [rasterLayer, vectorLayer],
        view: new ol.View({
            center: ol.proj.fromLonLat([35.1495, 33.39243]),
            zoom: 7
        })
    });

}

$.post("MapMarkers.php", null, null, "json")
    .done(data => {
        OpeNlayers(data)
    }).fail(function () {
        alert("error loading data")
    });
