Two external interrupts

Hello , im trying to use two external interrupts INT0,INT1 , just to use two limit switches but both dont work i dont know why ? here's the code i used.

void ex0_isr (void) interrupt 0
{
Motor3_2=0;
Motor3_3=0;
}
void ex1_isr (void) interrupt 1
{
Motor1_2=0;
Motor1_3=0;
}

void main(void)
{
// Initializations
IT0 = 1;   // Configure interrupt 0 for falling edge on /INT0 (P3.2)
EX0 = 1;
IT1 = 1;   // Configure interrupt 0 for falling edge on /INT0 (P3.2)
EX1 = 1;
PX0 =  1;
PX1 = 1;
// Enable EX0 Interrupt
EA = 1;    // Enable Global Interrupt Flag

Motor3_2=1;
Motor3_3=0;

Motor1_2=1;
Motor1_3=0;

while(1);
}
