JQuery :: Trigger DIV Loading Process According To Selectbox

I am currently using change and keyup to trigger a div loading process according to the select box. This works fine, when only mouse is used on the box. However, when the selection is made using arrow keys, this is what happens: Target div gets loaded fine, but when I click anywhere on the freshly loaded div content, it blinks. My guess is that change event is triggered after keyup, when it is not needed anymore. Is there an event or combination of events that detect selection change with both keys and mouse? Here's my simplified code:

<script type="text/javascript">
$(document).ready(function(){
$("#select_box").bind("change keyup", function(){
$("#result_div").load("some_data.php");
});
});
</script>
