How to make a keybinding?

[TesterTesting135]

Hello, so i have started java programming recently and i am making a mod that has armor that allows you to go into no-clip mode. (basically spectator mode) I want it so that when i press a key, it turns on no-clip, and sends a message to me. I think i can manage everything else but i'm having trouble registering the keybind. I have a KeybindHandler class which registers the keybind. I'm using MC 1.12.2. Code for my KeybindHandler:

public class KeybindHandler {

    public static KeyBinding keybind;

    public static void init() {
        keybind = new KeyBinding("No-Clip", Keyboard.KEY_SEMICOLON, "TestKeybind");
        ClientRegistry.registerKeyBinding(keybind);
    }

}

I'm not sure if i need to do anything else, other than this, but this by itself isn't working.

Any help would be greatly appreciated.
 

EDIT: The problem is the keybind doesn't show up in the controls section.

EDIT # 2: It looks like i forgot to call it... woops
