title: jQuery event delegation does not work for me
body: <p>I have an input with the class of <code>.mt-input-mini</code> </p>
  
  <p>This input is generated after the page load by clicking some other elements.</p>
  
  <p>I want to attach an event listener to this input, and thus I have used <code>on()</code> like this:</p>
  
  <pre><code> $('.mt-input-mini').on("click", function(event){               
              alert("Something has been done.");
          })
  </code></pre>
  
  <p>But this does not work. Why? I want to <code>alert()</code> on the click-event of this input.</p>
