title: jquery on() Proxy context unexpected
body: <p>This my code, basically, when tags_delete is clicked I would like to access id of the parent div. Somehow the context is not picked up. I have read the examples of $.proxy but can't get it to work.</p>
  
  <pre><code>&lt;div class="text"&gt;
  &lt;div id="894" class="tags"&gt;
  &lt;img height="24" src="image"&gt;
  &lt;a class="tags_delete"&gt;&lt;/a&gt;
  &lt;/div&gt;
  &lt;input id="tag_list" type="text"&gt;
  &lt;/div&gt;
  
  $("div.text").on("click", "a.tags_delete",          
                  $.proxy(function(that){                     
                      var imageId = that.parent("div").prop("id");        
                      console.log(that); 
                      console.log( imageId );
                      this.deleteTag(imageId);
                  }, this, $(this) )
          );
  </code></pre>
