A faster method would be to attach a single observer for all of the inputs.
Something like:
var InputsObserver = Class.create({
initialize : function(){
$("input-wrapping-element").observe("click",
this.inputsClickHandler.bindAsEventListener(this));
},
clickHandler : function(event){
var input = event.findElement("input");
if (input)
this.inputChangeHandler(input);
},
inputChangeHandler : function(input){
if (input.checked) { } // etc...
}
});
