Electronic – I2C: Unable to Read Multiple Byte using Bit-Banging method

I am using Bit-Banging for I2C communication via PIC24FJ128GA010.

The code works fine for writing 16bytes to EEPROM ( I recieved ACK = 0 for every Byte write ).

While reading EEPROM I am able to read only first Byte. Thereafter all bytes received are 0x00.

My EEPROM Device has 3 Pins ( Data_in, Data_out, CLK).

Here is my code.

I am unable to find the cause. Might be missing something.
Please help me finding the issue.

EDIT: I checked the data writted to the device by manually changing the Byte-addresses. And I can see all the data stored in the device. I guess internally address is not auto-increasing.
Is there a way out to command the device for auto increment or is there any logical issue in my code??
