Action Listener is not getting fired on click of button

Question

I am using a action listener event to upload documents on click of button. But when I click on the button it is not getting into the actionlistener method. But once I refresh the page the event starts working.

I tried invoking the event using phaseId as well ,but it is not working.

Let me know if I can do this in any other way.

My xhtml:

   <ace:fileEntry id="fileEntryForDocUpld" disabled="#{triggerRequestFormBean.disableDocUpload}" 
                                                                absolutePath="#{triggerRequestFormBean.uploadDirectory}"
                                                                maxFileCount="10"
                                                                maxFileCountMessage="Limited to 10 files uploaded concurrantly."
                                                                fileEntryListener="#{triggerRequestFormBean.uploadDocumentListener}"
                                                                required="false" useOriginalFilename="true"
