Is there a way to customize the value of a new tag? For example I want to create something like this:
`<option value="myCustomValue">The New Created Tag</option>`

I'm trying to do this, but is not working, and I can't find something on the documentación about this:

```
        createTag: function (params) {
            var term = $.trim(params.term);

            if (term === '') {
                return null;
            }

            return {
                id: term,
                text: term,
                newTag: true, // add additional parameters,
                value: "myCustomValue"
            }
        }

```
