jeditable dynamic target value

Question

I'm using jeditable and it works really great! I'm just having some trouble figuring out how to dynamically change the target URL.

jeditable is bound to a table of values that I want to edit inline. So I have:

<td id="<%= col.id %>_<%= i.id %>" class="edit">

The id is a mashup of two values I need to know to edit this item on the server side.

My js is:

    $(document).ready(function() {
 $('.edit').editable("/items/1", {
  id         : "column_id_item_id",

   submitdata : function(value, settings){
           return { data_template_id: '<%= @data_template.id%>}',  format : 'json'}
  } ,
  method     : 'PUT',  
 });
 });

Note the target url is "/items/1"
That /1 is what I need to change, and its one of the values built in to the td's id.

So my question is how do I take the value from the id of the element clicked and use it to modify the target parameter for jeditable.

Everything else is working fine, I'll just edit item 1 every time right now :)
