        $('.form-group right').each(function () {
            debugger;
            value = $(this).find("input[name='ValueRight']").val()
            label = $(this).find("input[name='LabelRight']").val()
            jsonArrRight.push({
                label: label,
                value: value
            })
        $('.form-group left').each(function () {
            value = $(this).find("input[name='ValueLeft']").val()
            label = $(this).find("input[name='LabelLeft']").val()
            jsonArr.push({
              label: label,
              value: value
           })
