attiny13 and timer interrupt

[inetd]

I can not enable interrupt on timer overflow at attiny13.
I just copied code from timer calculator(20ms period time) and add inverting pins in interrupt section. It must be equal the pwm with 50% duty cycle. And I expected to see 50% power of light on led.
But nothing happens on pins pb0 or pb1. Leds turned off and not blinking.
I tried to set TOIE0_bit = 1 without any changes.
Code is below. This code builds without any errors or warnings. Help please. I understand that it's something my very simple mistake, but I don't know how to correct it.

void InitTimer0(){
SREG_I_bit = 1;
OCR0A = 156;
TCCR0A = 0x82;
TCCR0B |= 0x05;
OCIE0A_bit = 1;
// TOIE0_bit = 1;
}

void Timer0Overflow_ISR() org IVT_ADDR_TIM0_COMPA {
//Enter your code here
PORTB0_bit = ~PORTB0_bit;
PORTB1_bit = ~PORTB1_bit;
}

void main() {

DDB1_bit = 1;
DDB0_bit = 1;

InitTimer0();

while (1)
{
};
}

Got it.
Need to set COM0A1 and COM0A0 to zeros for normal port operation.
So, TCCR0A must be changed to 0x2 in code generated from Timer Calculator.
