Hey Everyone!!

I've one checkbox:-

<asp:CheckBox ID="CheckBox1" runat="server" Checked="true" Width="140px" />Save My Details and Call me for Assistance




I've one button:-
<asp:Button ID="Button4" type="button" runat="server" Text="Compare Rates" OnClientClick="callme();" />


My Jquery functions are in as:-

<script type="text/javascript">

        $(function callme() {
            $('#CheckBox1').click(function () {
                if ($(this).is(':checked')) {
                    uservalid();
                }
            });
        });


        function uservalid() {
            var name, mobile, mail, query;
            name = document.getElementById("ContentPlaceHolder1_text10").value;
            mobile = document.getElementById("ContentPlaceHolder1_text11").value;
            mail = document.getElementById("ContentPlaceHolder1_text12").value;
            query = document.getElementById("ContentPlaceHolder1_text13").value;
            emailExp = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([com\co\.\in])+$/;

            if (name == "" && mobile == "" && mail == "" && query == "") {
                alert("Enter All Fields Mendatory!!");
                return false;
            }

            else if (name == "") {
                alert("Enter Name");
                document.getElementById("ContentPlaceHolder1_Text10").setAttribute("style", "border:solid 1px red;background-color:#E2D3DD");
            }

            else if (mobile == "") {
                alert("Enter Mobile");
                document.getElementById("ContentPlaceHolder1_Text11").setAttribute("style", "border:solid 1px red;background-color:#E2D3DD");
            }

            else if (mail == "") {
                alert("Enter Mail ");
                document.getElementById("ContentPlaceHolder1_Text12").setAttribute("style", "border:solid 1px red;background-color:#E2D3DD");
            }

            else if (mail != '') {
                if (!mail.match(emailExp)) {
                    alert("Invalid Email Id");
                    return false;
                }
                return true;
            }

            else if (query == "") {
                alert("Enter your Query");
                document.getElementById("ContentPlaceHolder1_Text13").setAttribute("style", "border:solid 1px red;background-color:#E2D3DD");
            }

        }
        </script>

Now I want if checkbox is checked onbutton click function callme() is executed which in turn calls function uservalid(). But I'm not able to do it. Please Help!!
