title: stop function on mouseup
body: <p>I've got a mousedown function.</p>
  
  <pre><code>$('#manRun').mousedown(function(e3) {
      var manID = get_id(this);
      e3.preventDefault();
      $(document).on('mousemove.moveMan, mousemove.slideMan', function(e2) {
         running(e2, runBtn, manID);
      });
  });
  </code></pre>
  
  <p>and a mouseup function to stop <code>running()</code></p>
  
  <pre><code>$('#manRun').on('mouseup', function(e) {
      e.preventDefault();
      $(document).off('mousemove.moveMan, mousemove.slideMan');
  });
  </code></pre>
  
  <p>but the <code>running()</code> function does not stop. How can I force <code>running()</code> to stop when the mouse is released?</p>
