p:autoComplete insert a new value to database - jsf

Question

I use in my project a p:autoComplete with multiSelection = true and forceSelection = false. I use it to add "tags" to my object.
This works indeed very good and is very useful.
Now I got a question and I hope it is possible to solve it.
Example
Tags stored in database: test, example
If I type test, or example, autocomplete makes a suggestion.
Now i would like to type:
primefaces
which is not found in db. Now I want to push this value from my autocomplete into the database.
How can I do that?

OK, I made up a solution, which works fine for me.
Primefaces autocomplete:
<p:autoComplete id="mulitAutoSchlagWorte"
value="#{entityHandler.entity.tags}"
completeMethod="#{entityListHandler.completeAreaWithCreation}"
var="_tag"
itemLabel="#{_tag.value}"
itemValue="#{_tag}"
multiple="true"
size="300"
converter="#{entityConverter}">
</p:autoComplete>
List Handler, which also creates a new Tag:
public List<Tag> completeAreaWithCreation(String query) {
List<Tag> returnList = this.entityManager.createNamedQuery(Tag.NAMED_QUERY_GET_TAGS_BY_LIKE, Tag.class).setParameter("tag", query.toLowerCase().trim() + "%").getResultList();
if(returnList.size() == 0){
if(query.endsWith(" ")){
entityHandler.create();
entityHandler.getEntity().value(query.trim());
entityHandler.save();
}
returnList = completeAreaWithCreation(query.trim());
}
return returnList;
}
