I am using odoo 11 and I as trying to make a custom js module containing the definition of a custom widget.

The official documentation at https://www.odoo.com/documentation/11.0/howtos/web.html is admittedly outdated and little of its content seems to be working in odoo 11.

By trial and error I managed to define the following js file, which at least does not appear to break as soon as it's loaded:

odoo.define('openacademy.test', function(require)
{
  "use strict";
  var Widget = require('web.Widget');
  var MyWidget = Widget.extend({
    start: function() {
        this.$el.append("<div>I am lost in the woods</div>");
    }
 });
});

If my understanding is correct, this should simply define a widget containing a simple html line and nothing else.

What should I do in order to insert this thing somewhere in a page? The way defined in the official docs does not seem to work on odoo11...

Thank you very much.
