jQuery Generated RSS Feed Title & Twitter's Data-Text

Hello,

I am trying to dynamically change twitter's data-text attribute based on the title of an rss feed that I am generating (btw I hope to do the same thing with the feed's url and twitter's data-url tag). Here is my code:

<script>
        var j=jQuery.noConflict();
          j(document).ready(function() { 
              jQuery(function($) {
              j("#bird-feeds")
            .rss("http://feeds.feedburner.com/patheos/Ukoy", {
                         layoutTemplate: '<dl>{entries}</dl>',
                         entryTemplate: '<dt><a href="#feed{index}">{title}</a></dt><dd id="feed{index}"><p><a href="{url}" id="birdurl{index}" class="feedurl"><h2 id="birdfeed{index}">{title}</h2></a><p>{body}</p></p></dd>',
                      });
                                    });
               });
        </script> 
          <div id="bird-feeds">

      <script>
        $(document).ready(function() {    
          $('#bird-tweet[data-text]').each(function(){
          $(this).attr('data-text', $('#birdfeed0'));
          $.getScript('http://platform.twitter.com/widgets.js');
         });
        });
      </script>


      <a href="http://twitter.com/share"
        class="twitter-share-button" id="bird-tweet"
        data-text="This is what we want to change dynamically"
        data-count="none">Tweet</a>

When I click my button, [object Object] loads into my tweet. Moreover, if I change the text within my attribute jQuery call from the function thats present now to static text like, "this is a test," it works. To put this simply, how can I place the entire generated contents of this line (<h2 id="birdfeed{index}">{title}</h2>) into my data-text string?

Thanks in advance for your thoughts and efforts.

You'll need to use the jQuery data() method. First argument "text", second the value.

Within that line is 

  $('#birdfeed0')

correct?

$(this).data('data-text', $('#birdfeed0'));

You don't need the "data-" in front. What element is the "#birdfeed0" you may need to call .text() on it for it's contents.
