Write to EEPROM on PIC

Question

Are there any PIC microcontroller programmers here?

I am learning PIC microcontroller programming using pickit2 and 16F690 chip that comes with it. I am currently working on various objects. I can successfully read the byte from the EEPROM in the code if I set the EEPROM vaklue to MPLAB, but I can't seem to change the value using the PIC itself. Just nothing happens and I do not read the changed value, do I always get the original, which implies that the recording is not working?

This is my code for this section, am I missing something? I know that I have a lot of unnecessary bank switches, I added most of them to make sure that being in the wrong bank is not a problem.

        ; ------------------------------------------------------
        ; Now SET the EEPROM location ZERO to 0x08
        ; ------------------------------------------------------

        BANKSEL EEADR
        CLRF    EEADR           ; Set EE Address to zero

        BANKSEL EEDAT
        MOVLW   0x08            ; Store the value 0x08 in the EEPROM
        MOVWF   EEDAT

        BANKSEL EECON1
        BSF     EECON1, WREN    ; Enable writes to the EEPROM

        BANKSEL EECON2
        MOVLW   0x55            ; Do the thing we have to do so
        MOVWF   EECON2          ; that writes can work
        MOVLW   0xAA
        MOVWF   EECON2

        BANKSEL EECON1      
        BSF     EECON1, WR      ; And finally perform the write

WAIT
        BTFSC   EECON1, WR      ; Wait for write to finish
        GOTO    WAIT

        BANKSEL PORTC           ; Just to make sure we are on the right bank
