    self._value = value;
    setTimeout(function () {
        self._listeners.forEach(function (listener) {
            listener.call(self, value);
        });
    });
};

    var views = Array.prototype.slice.call(document.querySelectorAll('[bind]'), 0);
    views.forEach(function (view) {
        var modelName = view.getAttribute('bind');
        models[modelName] = models[modelName] || new Model();
        models[modelName].bind(view);
    });
    callback.call(this, models);
}
