Search bar for open street map

I need help to add an functional search bar for this project. Like you search 'London' and get redirect to London, I'm having problems.

Here is my code for you guys:

var mymap = L.map("mapid").setView([-23.9608, -46.3331], 13);

L.tileLayer("https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", {
  maxZoom: 19,

    '<a href="https://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>, ' +
    'Imagery © <a href="https://www.mapbox.com/">Mapbox</a>',

  id: "mapbox.streets",
}).addTo(mymap);

L.marker([-23.9608, -46.3331])
  .addTo(mymap)

  .bindPopup("<b>Santos - SP </b>")
  .openPopup();

mymap.removeControl(mymap.zoomControl);

L.Control.geocoder({
  defaultMarkGeocode: false,

  placeholder: "Search address...",
}).addTo(mymap);

Here the fixed jsFiddle demo for you, click on the 🔍 icon to search:

The javascript code uses the Leaflet Control Geocoder by Mr. Per Liedman:

<!-- begin snippet: js hide: false console: false babel: false -->

<!-- language: lang-js -->

'use strict';

var myMap = L.map('mapId', { zoomControl: false })
	.setView([-23.9608, -46.3331], 13);

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
  maxZoom: 19,
  attribution: '© <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors'
}).addTo(myMap);

var marker = L.marker([-23.9608, -46.3331])
  .addTo(myMap)
  .bindPopup('<b>Santos - SP</b>')
  .openPopup();

L.Control.geocoder({
  defaultMarkGeocode: false,
  placeholder: "Search address...",
}).on('markgeocode', function(e) {
    var bbox = e.geocode.bbox;
    var poly = L.polygon([
      bbox.getSouthEast(),
      bbox.getNorthEast(),
      bbox.getNorthWest(),
      bbox.getSouthWest()
    ]).addTo(myMap);
    myMap.fitBounds(poly.getBounds());
  })
  .addTo(myMap);
