Question : Change content file onClick without reloading page.

My interface is here: http://brianfalls.com/playground/email_inerface_sandbox/emailTemplate/

The include:
<div id="emailContent">
      <div class="body">
            <cfinclude template="dsp/dsp_emailTemplate_#templateID#.cfm">
      </div>
</div>

The carousel instance:
<div id="featureCarousel" style=" float: left; ">
      <cfloop list="#request.templateist#" index="i" delimiters=",">
            <div class="feature">
                  <a onclick="alert('Change Emial Template...\r\nBut Only When Feature is Selected (At Center)...');"><img src="/playground/email_inerface_sandbox/templates/#i#/preview.png" /></a>
                  <div>
                        <p>
                              <h3>Template #i#</h3>
                              <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Aenean ornare egestas arcu eu auctor.</p>
                        </p>
                  </div>
            </div>
      </cfloop>
</div>

I am not sure where to go with it. How do I change the template without reloading? Further, how do I keep the click event to the primary feature only? I know, I will likely not be able to use cfinclude. It's just what I am using now. What do I use? I don't really want to use frames... I would like to keep it all as is, and just swap the included code for other included code. TIA!
