cc3200: Switch Interrupt in non-os.

I have gone through the email-example of cc3200. I  want to implement the interrupt in non-os ,So I have modified the code but it does not work . It does not go in to interrupt. Did I miss anything in configuration

Here is my code.

#include <stddef.h>
#include <string.h>
#include <stdlib.h>
#include <stdarg.h>
#include <stdbool.h>
#include <stdint.h>

and I have made P4 and P15 as inputs for sw2 and sw3  the PinMuxConfig(); as

    MAP_GPIODirModeSet(GPIOA1_BASE, 0x2, GPIO_DIR_MODE_OUT);

    //

    MAP_PinTypeGPIO(PIN_01, PIN_MODE_0, false);

    //
    // Configure PIN_57 for UART0 UART0_RX
    //
    MAP_PinTypeUART(PIN_57, PIN_MODE_3);
}

If anyone has done this before,please guide.

Thanks.
