I have the following settings in odoo 11, why the extend of form renderer is not working? I have tried the exact setting on the kanban view and it works nicely.
 
I am quite sure the javascript code is working, because if I log something in the extending of form view, I can see the message in the console of the browser.

odoo.define('module.my_form', function (require) {
    "use strict";

    var view_registry = require('web.view_registry');
    var FormView = require('web.FormView');
    var FormRenderer = require('web.FormRenderer')

    let myFormRenderer = FormRenderer.extend({
        init: function (parent, state, params) {
            this._super.apply(this, arguments);
            console.log("Hello")
        },
    })

    let myFormView = FormView.extend({
        config: _.extend({}, FormView.prototype.config, {
            Renderer: myFormRenderer
        }),
    });

    view_registry.add('my_custom_form', myFormView);
    return myFormView;
})
