How to bind checkboxlist in jquery

 <asp:CheckBoxList ID="chkListMY" runat="server" RepeatColumns="1">
  <asp:ListItem Text="" Value=""></asp:ListItem>
  </asp:CheckBoxList>

success: function (data)
    {if (data.length){
var repeatColumns = parseInt("<%=chkListMY.RepeatColumns%>");
 var cell = $("[id*=chkListMY] td").eq(0).clone(true);
  $("[id*=chkListMY] tr").remove();
for (var i = 0; i < data.length; i++)
  {
var row = $("<tr />");
$("[id*=chkListMY] tbody").append(row);
var checkbox = $("input[type=checkbox]", cell);                                                    //Set Unique Id to each CheckBox.
checkbox[0].id = checkbox[0].id.replace("0", i);                                                   //Give  text to each CheckBox.                        
checkbox[0].text = data[i].Text
//Set the CheckBox value.                                                  checkbox.val(data[i].Value);
var label = cell.find("label");
if (label.length == 0) {
label = $("<label />");
}
//Set the 'for' attribute of Label.
label.attr("for", checkbox[i].id);
//Set the text in Label.
label.html(data[i].Text);
//Append the Label to the cell.
cell.append(label);
//Append the cell to the Table Row.
row.append(cell);
cell = $("[id*=chkListMY] td").eq(0).clone(true);
};
}
}

<script type="text/javascript">
       
       
  
        $(document).ready(function () {       
            
  
getMonthYearCheckIndexChange();

</script>


function getMonthYearCheckIndexChange() {
            
            $("[id*=chkListMY] input[type=checkbox]").click(function () {
              
                var chks = $("[id*=chkListMY] input[type=checkbox]");
                var str = "";
                for (var i = 0; i < chks.length; i++) {
                    if (chks[i].checked) {
                        str = str + chks[i].text + ',';
                    }
                }
                str = str.substr(0, str.length - 1);
               alert(str);                
            });
        }

it initially shows empty check box in checkboxlist but my requirement is ,it(empty check box) should not be show.
And When I checked any checkbox it is working means calling given function
