Please look at the third row on this table. You should simply need to register mdlGetTimeOfNextVarHit as your Update function in the setup method:

block.RegBlockMethod('Update'  ,@mdlGetTimeOfNextVarHit);

Also, as a general suggestion, can I recommend that you change the name of mdlGetTimeOfNextVarHit to something more appropriate like 'Update'? C S-functions actually do have a method called mdlGetTimeOfNextVarHit, and it is best to avoid confusion with that.
