Bootstrap tooltip not working in chrome

Bootstrap Tooltip not working in chrome, but working fine in firefox.
<script type='text/javascript'>
jQuery(document).ready(function () {
if ($("[rel=tooltip]").length) {
jQuery("[rel=tooltip]").tooltip({
placement: 'right',
trigger: "hover"
});
}
});
</script>
And also the placement is not working correctly in firefox, even after
defining as right, its showing only on top.
