2 buttons with 2 different results

Question

I have a page that is going to ask a user to answer 'Yes" or 'No' to a question. If they click the 'Yes' button, they will go to a verification page. If they click the 'No' button, I want to display the same page, but with different text and a 'Try Again' button. how can I get these 2 buttons to work in jsf? Code examples would be very much appreciated.
Thanks

Here is my button code on my page:
<hx:commandExButton type="submit" value="Yes" styleClass="button" id="btnYes" action="#{Prescription_check.submit}" ></hx:commandExButton>
<hx:commandExButton type="submit" value="No" styleClass="button" id="btnNo" action="#{Prescription_check.submit}"></hx:commandExButton>
<hx:commandExButton type="submit" value="Try Again" styleClass="button" id="btnTryAgain" action="#{Prescription_check.submit}"></hx:commandExButton>When I click any of these buttons, I get a null pointer exception???? Here is the submit method in my backing bean:
public String submit() {
          FacesContext facescontext = FacesContext.getCurrentInstance();
          String returnValue = null;
          if (btnComponent.getId() == "btnYes") {
               ApplicationParameter.getLogger().debug("Yes button clicked");
               returnValue = ApplicationParameter.NAVIGATION_PRESCRIPTION_CHECK_YES;
               btnComponent.setRendered(false);
          if (btnComponent.getId() == "btnNo") {
               ApplicationParameter.getLogger().debug("No button clicked");
               returnValue = ApplicationParameter.NAVIGATION_PRESCRIPTION_CHECK_NO;
               btnComponent.setRendered(false);
          if (btnComponent.getId() == "btnTryAgain") {
               ApplicationParameter.getLogger().debug("Try Again button clicked");
               returnValue = ApplicationParameter.NAVIGATION_PRESCRIPTION_CHECK_NO;
               btnComponent.setRendered(false);
          return returnValue;
     }
