[Question] update Trait select option dynamically

I tried this to update trait selection.
var updateTrait = function(id, name) {

	var typeTrait = model.get('traits').where({name: 'type'})[0];
	var options = typeTrait.get('options');

	options.push({value: id, name: name});
	typeTrait.set('options', options);
};
But after click the element, it shows this error and the trait doesn't update.
