This will make your tabs load using ajax

<div id='tabs'> 
  <ul> 
    <li title='home'><a href="<?php echo url_for('post/index') ?>" title="Home">Home</a></li> 
    <li title='test'><a href="<?php echo url_for('post/test') ?>" title="Test">Test</a></li> 
  </ul> 
  <div id="home">home content here</div>
  <div id="test">test content here</div>
</div>
