             <div class="col-md-7">
                 <input type="checkbox" id="HealthStatusTrue" name="HealthStatus" value="true" class="healthstatus-checkbox" @(Model.HealthStatus == true ? "checked" : "") />
                 Yes
                 &nbsp;&nbsp;
                 <input type="checkbox" id="HealthStatusFalse" name="HealthStatus" value="false" class="healthstatus-checkbox" @(Model.HealthStatus == false ? "checked" : "") />

var HealthStatusData = new Object();
            HealthStatusData.HealthStatus = ???????????????
// how to get hidden field value here 
      }
</script>
