title: Simple jQuery UI Tooltip with no title attribute
body: <p>I'm trying to work with jQuery UI Tooltip and I think I may be missing something.</p>
  
  <p>I want the simplest possible tooltip to show up without specifying the title property.</p>
  
  <p>I believe I should be able to call this pretty much anywhere in my javascript:</p>
  
  <pre><code>$('#ContactName').tooltip({ content: 'Hey, look!' }).tooltip('open');
  </code></pre>
  
  <p>This is not working. Am I doing something wrong?</p>
  
  <p>EDIT: I should mention that #ContactName is an input[type=text], and it is in a jQuery UI dialog.</p>
  
  <p>EDIT 2: Okay this worked. I don't really understand why, though.</p>
  
  <pre><code>$($('#ContactName').parent()).tooltip({
      items: '#ContactName',
      content: 'Hey, look!'
  });
  </code></pre>
  
  <p>It works on hover. Is there anyway that I can, in the same code, make it open immediately?</p>
  
  <p>EDIT 3: This is what I ended up with:</p>
  
  <pre><code>            $($('#ContactName')).tooltip({
                  items: '#ContactName',
                  content: $(this).text(),
                  position: {
                      my: 'left+15',
                      at: 'right center'
                  },
                  tooltipClass: 'ui-state-error'
              }).tooltip("open");
  </code></pre>
