jQuery submit function is not working in following case and when I remove return false from this code then it starts working.
JavaScript
function insertQuotit() {
    jQuery.ajax({
        url: "<?php echo bloginfo('template_url')?>/quotitinsert.php",
        type: "post",
        data: jQuery('#quotitInsert').serialize(),
        success: function (res) {
            jQuery("#quotitInsert").submit();
        }
    });
    return false;
};
HTML
<form name="form1" method="post" id="quotitInsert" action="http://www.abc.net" >
<input type="submit" name="Submit" value="Submit" id="submit"  onclick="return insertQuotit();"/>
