How to submit a form after jQuery modal confirmation dialog?

Question

This script opens a jQuery dialog/modal to request verification prior to submitting the form, but when the user click on the "Submit" button in the modal window nothing happens. Firebug reveals that the issue is with the line containing, "document.leaveReq.submit();" I'm pretty new to jQuery and javascript, and have been struggling with this one for a few days. Any help here is much appreciated.

$(document).ready(function() {

    // jQuery UI Dialog    
    $('#dialog').dialog({
        autoOpen: false,
        width: 400,
        modal: true,
        resizable: false,
        buttons: {
            "Submit": function() {
                document.leaveReq.submit();
                return true;
            },
            "Cancel": function() {
                $(this).dialog("close");
                return false;
            }
        }
    });
    $('#formerror').dialog({
        autoOpen: false,
        modal: true,
        resizable: false,
        buttons: {
            "Back": function() {
                $(this).dialog("close");
                return false;
            }
        }
    });

    $('#verify').click(function(e){
        e.preventDefault();
        if( !$("input#from").val() || !$("input#to").val()){
            $("span#error-message").html('Provide a starting and ending date.');
            $('#formerror').dialog('open');
        } else if( $("input#amount").val() == 0 ){
            $('#formerror').dialog('open');
            $("span#error-message").html('Provide the number of units that you will use.');
        } else if( !$("textarea#description").val() ){
            $("span#error-message").html('Provide the reason for this leave request.');
            $('#formerror').dialog('open');
        } else {
                $("span#leavedescriptionidentification").html(document.getElementById('leave_description_identification').options[document.getElementById('leave_description_identification').selectedIndex].value);
            $("span#startingdate").html($("input#from").val());
            $("span#endingdate").html($("input#to").val());
            $("span#amount").html($("input#amount").val());
            $("span#description").html($("textarea#description").val());
            $('#dialog').dialog('open');
        }
        return false;
    });
});

In your Submit function on the dialog try:

"Submit": function() {
    $('form#leaveReq').submit();
    return true;
},
