Struts2: Help in autocompleter tag

[Sakthi Priya]

Am using struts 2.1.6

<%@ taglib prefix="sx" uri="/struts-dojo-tags" %>
....
....
<sx:head debug="true" cache="false" compressed="false" />
....
....
<sx:autocompleter list="enterpriseList" name="searchText" showDownArrow="false" dataFieldName="Enterprise"/>
....
....

Doubt:
My enterpriseList contains list of object Enterprise say id and name are the members. What attribute should i use in the autocompleter tag to fetch/do autocomplete based on the Enterprise' name

Thanks
