collisions

I have this code and the collision sensor is nor evaluated.

void collisonCallback( void *_ptr )
{
NSLog(@"collision");
}

//in templateLoading
sio2SensorInitCollision("mysensor", player, plane, collisonCallback);

//and in templateRender
sio2ResourceRender( gameResource,
sio2->_SIO2window,
gameCamera,
SIO2_RENDER_SOLID_OBJECT | SIO2_RENDER_TRANSPARENT_OBJECT | SIO2_RENDER_ALPHA_TESTED_OBJECT | SIO2_EVALUATE_SENSOR );

the physics in made in blender
player - dinamic-actor
plane - static -actor

Please give me a hint!

tnx
