ISSUE: How to add a new record to dataset of wizard list view via javascript

Version 7

What I am trying to Accomplish

• Using javascript in a web module I am trying to progamatically add/edit the records in the stock.picking.in receiving wizard
• But I am having no success in accessing the javascript object that represents the list view with the dataset
• I have created a web module with a javascript file that attempts to inherit the instance.web.ListView of the wizard form but none of my custom events are able to access the dataset of the wizard form

code example from my javascript file:

openerp.test_access = function(instance) {
    var _t = instance.web._t,
        _lt = instance.web._lt;
    var QWeb = instance.web.qweb;

    instance.test_access = {};

    instance.web.views.add('test_access', 'instance.test_access.wizard');

    instance.test_access.wizard = instance.web.ListView.extend({
        init: function() {
            this._super.apply(this, arguments);
        },
        start: function() {
            var tmp = this._super.apply(this, arguments);
            var self = this;
            return tmp;            
        },
}
