[web2py] Ajax and table rows.

[tsvim]

Hi all,

I'm trying to have a ajax callback function whenever I click a certain row. 
I'd like that row to return the id of the record the row represents.
I'm at loss as to the middle argument for the ajax function. I checked the 
function in the controller gets called but the argument is wrong.
I created a simple example so I could try and traceback the problem but I 
think I'm doing something wrong.

This is my view:

{{extend 'layout.html'}}

<table>
    <tr class="row" id="1" onclick="ajax('echo', ['id'], ':eval')">
        <td>Hello</td><td>World</td>
    </tr>
    <tr class="row" id="2" onclick="ajax('echo', ['id'], ':eval')">
        <td>Row 2</td><td>New world</td>
    </tr>        
</table>
        
<div id="target"></div>

And the following is my controller:

def one():
    return dict()
    
def echo():
    return "jQuery('#target').html(%s);" % request.vars.id

What am I doing wrong?
