how to access dom element attribute in plugin settings

how to access dom element attribute in plugin settings

How can I assign different values to plugin parameters based on dom element - this - attributes?

Say I have 4 elements:

<div class="editme" id="friuts" rel="one">apples</div>
<div class="editme" id="numbers" rel="two">5,6</div>
<div class="editme" id="candy" rel="three">gum</div>
<div class="editme" id="shapes" rel="four">circle</div>


.. that I bind a jquery behavior to:

$('.editme').editable('savedata.php',{
   loadurl   : 'loaddata.php',
});


.. now I want to pass different parameters to the jquery plugin based on the dom element being manipulated.
for example I want to pass the value of the div's rel attribute like this:

$('.editme').editable('savedata.php',{
   loadurl   : 'loaddata.php',
   loaddata  : {regarding: function(){ return eval($(this).attr('rel'))}}
});


.. but this does not work.. how should it be done?
