You are not clearing the TIMER when the compare value (CC[0]) is reached, which means that the timer will count until it overflows after 2^16 / 250kHz = 262ms. You can setup the timer to be cleared at compare value 0 with shorts:

NRF_TIMER1->SHORTS = (TIMER_SHORTS_COMPARE0_CLEAR_Enabled << TIMER_SHORTS_COMPARE0_CLEAR_Pos);

Then you should get interrupt every 1ms.
