title: jQuery and load(). Unable to change inner HTML in loaded class
body: <p>I'm trying to change inner HTML in loaded div by this function:</p>
  
  <p><code>$("#container").load("site.php");</code></p>
  
  <p>In <code>site.php</code> I have <code>&lt;div class="users_count"&gt;</code> and I would like to put some text inside it. I'm trying to use <code>$(".users_count").html("TEST")</code> but it can't be done since jQuery do not see <code>.users_count</code> class. </p>
  
  <p>I've heared about jQuery <code>on()</code> and <code>live()</code> but it requires some event like <code>click, keyup etc...</code> </p>
  
  <p>I need to put some text in this div without any event - just do it in my function without user action.</p>
