title: Backbone change event not fired for select field selected by jQuery
body: <p>I have a button that when clicked sets the value of a select field and also have a change event for the select field. The 'change select[name=location_id]' event works when selecting normally via mouse/keyboard but clicking the button, which uses jQuery to change the select field value, doesn't fire off the 'change select[name=location_id]' event.</p>
  
  <p>How do I get the 'change select[name=location_id]' to fire when changing the field via jQuery?</p>
  
  <pre><code>SubscriptionsModule.Views.SubscriptionEditView = Backbone.Marionette.LayoutView.extend({
      template: "subscriptions/edit",
      events: {
        'click #home-delivery-select': 'selectHomeDeliverySite',
        'change select[name=location_id]': 'updateLocation'
      },
      selectHomeDeliverySite: function() {
        this.$el.find('select[name=location_id]').val(this.model.get('hd_location_id'));
      },
      updateLocation: function(e) {
        //update location code
      },
      updateOrderSize: function(e) {
        SubscriptionsModule.eventManager.trigger('updateOrderSize', $(e.currentTarget).data('price'));
      }
    });
