我的数据表中有一个复选框和文本框。按下更新按钮后，我需要更新数据库。

请在 test.xhtml 下面查看我的代码

         <p:column headerText="Enable"  style="width:13%" >  
              <p:selectBooleanCheckbox  id="chkEnable" />  
        </p:column>  

        <p:column headerText="Description">  


                  <p:inputText id="modelInput" value="#{generalServiceBean.manufacturers}" style="width:96%"/>




        </p:column>  



        </p:dataTable>


                 <h:panelGrid columns="1" cellpadding="5" columnClasses="col1,col2">
                  <p:column >                  
                    <h:outputText value="Check all / Uncheck all " />  
                          <p:selectBooleanCheckbox value="" />  
                  </p:column>

                     <p:column >                  



                      <p:commandButton id="btnUpdate" value="Update" action="#{generalServiceBean.saveBook}" ajax="false"  />

                  </p:column>

            </h:panelGrid>



         <br/>




      </p:panel>
    </h:form>

        </h:form>
      </p:outputPanel>
    </p:confirmDialog>
  </ui:define>
</ui:composition>
</html>

所以我有问题当我按下更新按钮时如何获得数据表的结果？
