Why does the jquery change event not trigger when I set the value of a select using val()?

Question

The logic in the change() event handler is not being run when the value is set by val(), but it does run when a user selects a value with their mouse. Why is this?

<select id="single">

    <option>Single</option>

    <option>Single2</option>

</select>

<script>

    $(function() {

        $(":input#single").change(function() {

           /* Logic here does not execute when val() is used */

        });

    });

    $("#single").val("Single2");

</script>

You just have to use a textarea to get multiline handling like this:

<textarea name="Text1" cols="40" rows="5"></textarea>
