Dynamically set mapview based on the overlay feature of L.geoJson coordinates in Leaflet

    I want to dynamically setView of the map based on the overlay feature which I extract from L.geoJson in Leaflet. I tried using fitBounds, which doesn't seem to work. Here is the code snippet:

    var counties = $.ajax({
    url:"http://localhost:8080/geoserver/........../&maxFeatures=50&outputFormat=application/json",
    dataType: "json",
    success: console.log("data successfully loaded."),
    error: function (xhr) {
    alert(xhr.statusText)
    }
    })

    $.when(counties).done(function(){
    var map = L.map('map')
    .setView([52.30, 8.23], 15); //I want to set the coordinates dynamically here like setActiveArea
    // .setActiveArea('activeArea', true, true);

    // Map layer

    var Esri_WorldImagery = L.tileLayer('https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}', {
    attribution: 'Tiles © Esri — Source: Esri, i-cubed, USDA, USGS, AEX, GeoEye, Getmapping, Aerogrid, IGN, IGP, UPR-EGP, and the GIS User Community'
    }).addTo(map);

    //Style layer for counties
    var geojsonMarkerOptions = {
    radius: 8,
    fillColor: "#ff7800",
    color: "#000",
    weight: 1,
    opacity: 1,
    fillOpacity: 0.8
    };

    // Add requested external GeoJSON to map
    var ky = L.geoJSON(counties.responseJSON, {
    style: geojsonMarkerOptions
    }).bindPopup(function (layer) {
    return ("Name of the field:"+(layer.feature.properties.name)+'<br/>'+"Name" +(layer.feature.properties.sid)+"sid");
    }).addTo(map);

    //Just a try, doesnt seem to work either
    ky.on('load', function() {
    map.fitBounds(ky.getBounds(), {maxZoom: 3});
    });
    });


    I tried using Leaflet plugin https://github.com/Mappy/Leaflet-active-area but got a blank output. Is there any other way to dynamically use the overlay coordinates and set it as a map view?
