'changed' event fires when list is not changed

The selection is not changed when clicking in the list. You need to actually select the option. Therefore:

```
L.DomEvent.addListener(this._fullist, 'click', this._onListChange, this);
```

should be changed to

```
L.DomEvent.addListener(this._fullist, 'change', this._onListChange, this);
