Cannot find void methods in MainViewModel

[RobIsr]

In todo_item.xml I am setting the "onClick" attribute to the LinearLayout which, in turn, contains the cardview with the note. As below I am using the removeNote() method from MainViewModel and passing in the position variable like below:

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="16dp"
    android:orientation="vertical"
    **android:onClick="@{() -> viewModel.removeNote(position)}">**

When I try to make the removeNote function a void function I cannot find it from the xml. The only solution that worked for me was to make it return something. So even if it doesnt need to I made return a boolean just to find it:

    //This function removes a note from the database and sets a new Adapter with the updated list of notes.
    public boolean removeNote(long id) {
        //Call mDb.delete to pass in the TABLE_NAME and the condition that WaitlistEntry._ID equals id
        mDb.delete(ToDoContract.TodoEntry.TABLE_NAME, ToDoContract.TodoEntry._ID + "=" +
                String.valueOf(id), null);
        MainActivity.mTodoRecyclerView.setAdapter(new ToDoAdapter(allNotes(), this));
        Log.d(TAG, "removeNote: " + "clicked");

        return true;
    }

I am trying to figure out why this is, and if there is a way to call void functions and still pass them parameters.
