primefaces DataExporter ignore columns that have h:link

Question

the primefaces DataExporter ignores the the column where I use to link the result.

<p:column>
            <f:facet name="header">
                <h:outputText value="Brand" />
            </f:facet>
         <h:link outcome="pretty:carBrand-page">
            <h:outputText value="#{car.brand}" />
         </h:link>
 </p:column>

How can I get the brand also exported, without href ? Thanks
