JQuery :: Binding Multiple Elements Without Using Selector

I am learning jQuery now and have a big interest in this javascript framework. I am trying to bind an event to more than one element. I won't meet any problem if using selector. But now, I've created a function which I will pass the element. And I need within this function, to bind the code. This is my current code :

function updateDay(dayObj, monthObj, yearObj){
//I want to bind both monthObj and yearObj.
yearObj.change(function(){
//do something
});
monthObj.change(function(){yearObj.change()});
}
$(document).ready(function(){
updateDay( $("#day"), $("#month"), $("#year"));
});

As you can see, I must bind twice, once for yearObj, the other for monthObj. Is there anyway to bind the change() event only once? If there are some logic mistake in using function or such as feel free to point out, since I still haven't read all the documentation yet.
