title: How to make p:graphicImage clickable and invoke bean action
body: <p>I am using <code>&lt;p:graphicImage&gt;</code> like below:</p>
  
  <pre><code>&lt;div id="mapp"&gt;
      &lt;h3&gt;Country Map&lt;/h3&gt;         
      &lt;p:graphicImage id="city"
                      value="#{countryPages_Setup.countryMap}"
                      width="250"
                      height="190"&gt;
  
       &lt;/p:graphicImage&gt;                
  &lt;/div&gt;
  </code></pre>
  
  <p>But this is not a clickable image. How can I make this image clickable so when user click on it, I can invoke the managed bean action that I want.</p>
