I confess I am not the JavaScript expert, but I suspect the reason 
you're having difficulty is because an element attribute is usually 
considered a child of the element.  Were I to hazard a guess, you'd need 
to look at something like:

function coolHandler(event)
{
   var d = dashcode.getDataSource("list");
   var n = d.selection().valueForKey("name.water_id");
     alert( n );
}
