You could use the function that changes the text of span1 to change the text of the others.

As a work around, if you really want it to have a change event, then don't asign text to span 1. Instead asign an input variable in jQuery, write a change event to it, and whever ur changing the text of span1 .. instead change the value of your input variable, thus firing change event, like so:

var spanChange = $("");
function someFuncToCalculateAndSetTextForSpan1() {
    //  do work
    spanChange.val($newText).change();
};

$(function() {
    spanChange.change(function(e) {
        var $val = $(this).val(),
            $newVal = some*calc-$val;
        $("#span1").text($val);
        $("#spanWhatever").text($newVal);
    });
});

Though I really feel this "work-around", while useful in some aspects of creating a simple change event, is very overextended, and you'd best be making the changes to other spans at the same time you change span1.
