Validating CheckboxList

I'm using this form validation with text fields. However, I'm not getting it at all with checkboxList. Is there any way to do this? Follow the code below.

function form_validation() {
        $("#aspnetForm").validate({
            errorElement: 'span',
            errorClass: 'help-block',
            rules: {
                ctl00$ContentPlaceHolder1$txtDataInicioEmissao: {
                    required: true
                },
                ctl00$ContentPlaceHolder1$txtDataFimEmissao: {
                    required: true
                },
                ctl00$ContentPlaceHolder1$chkLstOrigem: {
                    checkrequired: true
                }
            },
            messages: {
                ctl00$ContentPlaceHolder1$txtDataInicioEmissao: {
                    required: "<%= Resources.UIResource.PreenchaOcampo %>"
                },
                ctl00$ContentPlaceHolder1$txtDataFimEmissao: {
                    required: "<%= Resources.UIResource.PreenchaOcampo %>"
                }
            },
            highlight: function (element) { // entradas de erro do hightlight
                $(element)
                    .closest('.form-group').removeClass('has-success').addClass('has-error'); // definir a classe de erro no form-group
            },
            unhighlight: function (element) { // reverter a mudança feita pelo hightlight
                $(element)
                    .closest('.form-group').removeClass('has-error'); // definir a classe de erro no from-group
            }
        });
        return true;
      }
