nrf51822EK on kit button triggering

I have burnt ble-app-multilink peripheral code on my nrf51822ek. What happens currently is dat when i press button on kit, on kit led turns on . when i press it again, it turns off.

I require that when button is in pressed state it, the led should remain on and when it is released it should turn off.

How is this possible ? any sort of help will be appreciated.
