Leaflet routing machine error: Geocoder is undefined

Question

Having a problem with leaflet routing machine. The very basic code

var routingtest = L.Routing.control({
        waypoints: [
            L.latLng(57.74, 11.94),
            L.latLng(57.6792, 11.949)
        ]
}).addTo(mymap);

does run fine.

But as soon as I add more code like described at http://www.liedman.net/leaflet-routing-machine/tutorials/ I get errors. For example this does not work:

var routingtest = L.Routing.control({
    waypoints: [
        L.latLng(57.74, 11.94),
        L.latLng(57.6792, 11.949)
    ],
    routeWhileDragging: true,
    geocoder: L.Control.Geocoder.nominatim()
}).addTo(mymap);

It throws back TypeError: L.Control.Geocoder is undefined. I just redownloaded the plugin to make sure nothing has been accidentially modified, but still. My index.html looks like this:

<div id="map" class="map"></div>
<!-- custom script containing routing machine and other stuff (which works all fine)!-->
<script type="text/javascript" src="javascript/myscript.js"></script>
</body>
</html>

Paths to .js and .css files are all fine.

My leaflet map var with one of the basemaps looks like this:

var mymap = L.map('map', {
    center: [57.89, 12.02],
    zoom: 13.5,
    fullscreenControl: true
});

var osm = L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png',
{ attribution: '&copy; <a href="http://osm.org/copyright" target = "_blank">OpenStreetMap</a>'
}).addTo(mymap);

What could cause the TypeError: L.Control.Geocoder is undefined error and how to fix it?
