question about get wpd driver value from metro javascript

Question

I want get the value back in wpd driver to my metro UI.

in my wpd driver, I have setting the value as below:

MethodParameterAttributeInfo g_ServiceMethodParameters[] =
{
    {&METHOD_ReadHeartRateMeasurement, &METHOD_PARAMETER_HealthHeartRateService_Measurement_Result,                VT_BOOL,    WPD_PARAMETER_USAGE_RETURN, WPD_PARAMETER_ATTRIBUTE_FORM_UNSPECIFIED, 0, L"Result" },
    {&METHOD_ReadHeartRateMeasurement, &METHOD_PARAMETER_HealthHeartRateService_Measurement_Value,             VT_INT,     WPD_PARAMETER_USAGE_OUT,    WPD_PARAMETER_ATTRIBUTE_FORM_UNSPECIFIED, 1, L"Value" },
   
};

HRESULT HealthHeartRateService::OnMethodInvoke(
    _In_    REFGUID                Method,
    _In_    IPortableDeviceValues* pParams,
    _Out_   IPortableDeviceValues* pResults)
{
    HRESULT hr = S_OK;
    
    UNREFERENCED_PARAMETER(pParams);
    
    if (IsEqualGUID(METHOD_ReadHeartRateMeasurement, Method))
    {

       READVALUE_MEASUREMENT * pMeasurement = NULL;

       int value=50;

       if (SUCCEEDED(hr))
            {
                hr = pResults->SetUnsignedLargeIntegerValue(METHOD_PARAMETER_HealthHeartRateService_Measurement_Value, value);
                CHECK_HR(hr, "Failed to add METHOD_PARAMETER_HealthHeartRateService_Measurement_Value");
            }

        return hr;

    }

How to get METHOD_PARAMETER_HealthHeartRateService_Measurement_Value = 50 back to my metro UI?
