How to eanable and diable actions in backoffice?

I have created one action for product synchronization using backoffice hybris 6.3. It is working for list view but the same button is not enabling in editor area it is always disabled. I have used the below configuration

     <y:actions xmlns:y="http://www.hybris.com/cockpit/config/hybris" >
         <y:group qualifier="common">
             <y:label>actiongroup.common</y:label>
             <y:action action-id="xyz.backoffice.actions.ProductSynchronizationAction" property="currentObject" />
         </y:group>
     </y:actions>
 </context>
 <context merge-by="type" type="Product" component="listviewactions">
     <y:actions xmlns:y="http://www.hybris.com/cockpit/config/hybris" >
         <y:group qualifier="common">
            <y:action action-id="xyz.backoffice.actions.ProductSynchronizationAction" property="selectedObjects"/>
         </y:group>
     </y:actions>
 </context>
