STM3232746g_discovery demo gesture problem

I'm trying to add to the ST Demo, the gesture recognition functionality provided by the touch screen. In the timer callback k_TouchUpdate, I added the following code, but the returned value is always zero.
How can I get it work?

uint8_t  gesture;

BSP_TS_GetState((TS_StateTypeDef *)&ts);

if(ts.touchDetected>1) { //>Multitouch        
        gesture = BSP_TS_Get_GestureId(&ts);
}

Thanks,
