Should add f:setPropertyActionListener

<p:commandButton id="viewButton" value="View" icon="ui-icon-search"  
               update=":form:display" oncomplete="carDialog.show()"    actionListener="#{tableBean.add}"
                >  
         <f:setPropertyActionListener value="#{car}" target="#{tableBean.selectedCar}"/> 
</p:commandButton>
