As tjkj2002 says, you have to buy the whole door panel. Cheapest place to look would be junkyards. Hopefully you have a common trim level and colour, so you don't have to check too many before you find a matching panel.
Just FWIW, a brand-new panel will set you back anything from $360-460 from an online Mopar parts discounter (more from a dealership) depending on the trim level. There are dozens of different part numbers for the door panel in the catalog, to cover all the various trim and colour options, so you need to know the specific trim code for your KJ.
