I know for ISIS there is no concept of router-ID however when you check routing table it gives you the IP address of originating router-ID .. Now the question what is this IP address and how could we change it ?

Its been a long time digging the TLVs :). IIH and LSP will carry "IP Interface Address" (code point 132) which in turn carries the IP address. In case of IIH, it carries the interface address and in LSP, it carries the lowest address with /32 subnet (If my memory serves me right).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
