Not able to call Button Click event

Question

Hi,

I have crated one control. Put some textbox and dropdown list as I required. I have created one button called submit. Which is not firing any event.
When I am click that submit button It is firing required field validation but after filling all the details it is not firing any events.

Need help ASAP.

I have pasted a control file here with :

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="RaiseOutboundRequest.ascx.vb"
    Inherits="AFT.Web.RaiseOutboundRequest" %>
<%@ Register Assembly="GMDatePicker" Namespace="GrayMatterSoft" TagPrefix="cc1" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>
<script type="text/javascript" language="javascript">
    function CalculatePayment() {
        var txtPaidByCustomer = document.getElementById('<%=txtPaidByCustomer.ClientID%>');
        var txtPaidBySigma = document.getElementById('<%=txtPaidBySigma.ClientID%>');
        if (txtPaidByCustomer != null && txtPaidBySigma != null) {
            var paidByCustomer = txtPaidByCustomer.value;
            if (isNaN(paidByCustomer) || paidByCustomer <= 0 || paidByCustomer > 100)
                txtPaidBySigma.value = 100;
            else
                txtPaidBySigma.value = parseInt(100 - paidByCustomer);
        }
    }
    function RaiseOutboundRequestCounterControl() {
        var lblRaiseOutboundRequestCharCounter = document.getElementById('<%=lblRaiseOutboundRequestCharCounter.ClientID%>');
        return lblRaiseOutboundRequestCharCounter;
    }
    function ShowHideAirFreightRecoverDetails() {
        var ddlAirFreightChargeMethod = document.getElementById('<%=ddlAirFreightChargeMethod.ClientID%>');
        var ddlAirFreightChargeMethodText = ddlAirFreightChargeMethod.options[ddlAirFreightChargeMethod.selectedIndex].text;
        var trPaidByCustomer = document.getElementById('<%= trPaidByCustomer.ClientID%>');
        var trPaidBySigma = document.getElementById('<%= trPaidBySigma.ClientID%>');
        var trAttachCustomerBDVApproval = document.getElementById('<%= trAttachCustomerBDVApproval.ClientID%>');
        ShowHideAirFreightRecoveryMethod(ddlAirFreightChargeMethodText, trPaidByCustomer, trPaidBySigma, trAttachCustomerBDVApproval);
    }
    function ShowHideAttachCustomerBDVApprovalDetails() {
        var txtPaidByCustomer = document.getElementById('<%=txtPaidByCustomer.ClientID%>').value;
        var trAttachCustomerBDVApproval = document.getElementById('<%= trAttachCustomerBDVApproval.ClientID%>');
        ShowHideAttachCustomerBDVApprovalMethod(txtPaidByCustomer, trAttachCustomerBDVApproval);
    }
