Using up a timer

I'm trying to implement a Sparkfun weather station using an mDot with UDK dev board.

The code below is part of some example code gotten from the mbed resources.

I do not believe the ISR - timer scheme is actually running (a temporary printf in it never produces output). Can someone point to a step I may be missing?

*/
#include <mbed.h>
#include "Anemometer.h"

#define REV_PER_SECOND_TO_KMPH  2.4f
CAnemometer::CAnemometer(PinName AnemometerPin, unsigned int IgnoreTimeForDebounceInMicroSeconds)
    : CDebouncedFallingEdgeCounter(AnemometerPin, IgnoreTimeForDebounceInMicroSeconds)
{
    m_CurrentWindSpeed = 0.0f;
    ResetMaximumWindSpeed();
    m_OneSecondTicker.attach_us<CAnemometer>(this, &CAnemometer::OneSecondTickerISR, 1000000);
}

...

void CAnemometer::OneSecondTickerISR()
{
    unsigned int GetCurrentCount = GetCountAndZero();
    m_CurrentWindSpeed = (float)GetCurrentCount * REV_PER_SECOND_TO_KMPH;
    if (m_CurrentWindSpeed > m_MaximumWindSpeed)
    {
        m_MaximumWindSpeed = m_CurrentWindSpeed;
    }
}

My main.cpp has this line

CWeatherMeters  weathermeters( WINDSPEED_PIN, RAIN_GAUGE_PIN, WINDDIR_PIN );

and the file weathermeters.cpp has 

CWeatherMeters::CWeatherMeters(PinName AnemometerPin,
                               PinName RainGaugePin,
                               PinName WindVanePin,
                               float   WindVaneSeriesResistance) : m_Anemometer(AnemometerPin),
                                                                 m_RainGauge(RainGaugePin),
                                                                 m_WindVane(WindVanePin, WindVaneSeriesResistance)
{
}
