Check Box Will Not Disable When Checked, android studio

Just like the title says, I have done some research and altered my code but still when I run it, it does not disable. Any idea why?

 cb_leic.setOnCheckedChangeListener( new CompoundButton.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton arg0, boolean isChecked) {
if(isChecked){
cb_leic.setEnabled(false); // disable checkbox
  }
  }
 } );
