CreateDataTimer is a wrapper for CreateTimer, perhaps understanding what it does might help you.

/**
 * Creates a timer associated with a new datapack, and returns the datapack.
 * @note The datapack is automatically freed when the timer ends.
 * @note The position of the datapack is not reset or changed for the timer function.
 *
 * @param interval			Interval from the current game time to execute the given function.
 * @param func				Function to execute once the given interval has elapsed.
 * @param datapack			The newly created datapack is passed though this by-reference 
 *							parameter to the timer callback function.
 * @param flags				Timer flags.
 * @return					Handle to the timer object.  You do not need to call CloseHandle().
