Segue abaixo meu codigo


<h:form id="form" >


 <p:dataTable id="multiCars" var="car" value="#{tableBeann.mediumCarsModel}" paginator="true" rows="10"  
                 selection="#{tableBeann.selectedCars}">  
  
        <f:facet name="header">  
            Checkbox Based Selection  
        </f:facet>  
  
        <p:column selectionMode="multiple" style="width:2%" />  
  
        <p:column headerText="Model" style="width:25%">  
            #{car.model}
