Linkbutton To Expand Gridview Causes Row Colors From Function To Be Lost

When a Link button I have in my gridview that expands the table to show a nested gridview i lose all the row colors that i get from this function. What I need is a way to call the function when the link button is clicked.

<script type="text/javascript">
$(document).ready(function () {
$("#<%=GridView1.UniqueID%> tr").each(function () {
var status = $(this).children('td:eq(6)').text();
if (status == 'OK') {
$(this).children('td').css({ "background-color": "lightgreen" });
}
else if (status == 'XL') {
$(this).children('td').css({ "background-color": "RED" });
}
else if (status == 'CL') {
$(this).children('td').css({ "background-color": "YELLOW" });
}
})
});
</script>
