how to pass selected value in rich:autocomplete

[jyothi nalam]

I have a datatable which displays the to email addresses and also I have a rich:autocomplete used to select the email address. I am able to display the address selected, but I am not able to send the selected address and update the datatable.

                                             <s:div id="divEmailTo">
				                	<h:outputText value="No To address selected" rendered="#{empty manager.info.emailTos}"/>
					                <rich:dataTable style="width:30%;" id="dtlEmailTo" value="#{manager.info.emailTos}" var="email"
					                	rendered="#{not empty manager.info.emailTos}">
					                	<rich:column>
					                		<h:outputText value="#{email}" />    
					                	</rich:column>
					                	<rich:column>
					                		<a:commandLink ajaxSingle="true"
					                		 	action="#{manager.deleteEmailTo(email)}" 
					                		 	id="deletelink"
						                     	reRender="divEmailTo">
						                        <h:graphicImage value="img/delete.gif" style="border:0" />	                        
						                    </a:commandLink>
					                	</rich:column>	
					                </rich:dataTable>
				                </s:div>
                                                <rich:autocomplete  autocompleteMethod="#{dBUtil.autoSuggestEmail}" id="sugEmailTo"
							 	 mode="ajax" minChars="1" autoFill="false"  var="obj" fetchValue="#{obj.email}" layout="table" onselectitem="#{rmaManager.assignSelectedToEmail(this.value)}"
							 	 reRender="divEmailTo">
							 		<h:inputHidden name="emailId" value="#{obj}" id="emailId"  />
								 	<rich:column>
						              <h:outputText value="#{obj.firstName} #{obj.lastName}" />
						            </rich:column>            
				               </rich:autocomplete>

I tried different ways of calling a jsfunction and assign the variable . but I couldnt get it to working. Please help with some suggestions. when I kept an alert(this.value) inside onselectitem, it displayed the value of the email address, but when I sent the same to the backing bean, I have a null value.

Thanks,
