"could be done by jumping to the init location. is this the fault? "

In the links section <<<--- I have, in the last group, placed a link to the Intel "bible". Clearly you lack some basic understanding, download it and save the first 3 chapters. Then, in the Hardware description chapter under Interrupts (3-23 in the printed version) you will find little tidbits such as "the processor acknowlwdges an interrupt request by executing a hardware gebnerated LCALL" = push on the stack. Also, you will find that an interrupt is not reactivated till a reti happens.

Read and learn
