Help ALT+C Command on L2jaCis

Hello guys! Somehow i manage to put some horses as "mounts" in the game they work the same as an Strider (its a copy with another skin). But when i summon the horse the "mount/dismount" button never appears. So i thinks i'ts because the HMTL on the alt+c tab "Actions" needs a new exception for the new mount in the code. but i can't find the .java class on the source. or even the html. im new in this kind of stuff, pls i need help. i work with the rev 379 on windows 10 64 bits. also i have some pictures. ask me everything.
