Hello, I made this JS to add a functionality on a form (backend) that computes a field when the event click is triggered. So far the code recomputes when I use .include but the whole js in all views fails since I'm using .include. When i try to use extend, looks like Odoo  doesn't add the extended code to the js engine so my question is, what am I doing wrong here? Is there something else i need to add so my code as extended works?

PD. Somehow I can't add tags to this question

odoo.define('med_care.TestRenderer', function (require) {
"use strict";

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

    var TestFormRenderer = FormRenderer.extend({
        events: _.extend({}, FormRenderer.prototype.events, {
            'click .selector_simbolo': '_onSelectorSimboloClicked',
        }),
        init: function (parent, state, params) {
            this._super.apply(this, arguments);
            this.fields = state.fields;
            this._onSelectorSimboloClicked = _.debounce(this._onSelectorSimboloClicked, 300, true);
        },
        confirmChange: function (state, id, fields, e) {
            var self = this;
            if (state.model == 'med.test') {
                return this._super.apply(this, arguments).then(function () {
                    self.canBeSaved(self.state.id);
                });
            }
        },
        _onSelectorSimboloClicked: function (event) {
           this.state.data.telefono = '333';
           if (this.state.model == 'med.test') {
               var info_test = {
                   dataPointID: this.state.id,
                   changes: {telefono: '333'},
                   viewType: "form",
                   notifyChange: true
               };
               var odoo_event = this.trigger_up('field_changed', info_test);
               this.confirmChange(this.state, this.state.id, "telefono",          
               odoo_event)
            }
        },
    });
    var TestFormView = FormView.extend({
        config: _.extend({}, FormView.prototype.config, {
            Renderer: TestFormRenderer,
        }),
    });
    viewRegistry.add('test_form', TestFormView);
    return TestFormView;
});
