Android Activity doesn't enter onBackPressed() method

This is an Activity of my Android App: for now I'm just testing that the going back to another activity works well. The problem is: when I hit the back button everything happens normally, but when I press the back arrow in the top left of the screen in the ActionBar, the activity doesn't enter the onBackPressed() method (and so the other activity crashes because it's expecting an intent passed). Any ideas on how to solve this?

package com.example.thefe.newsmartkedex;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;

/**

public class MyPokeDetails extends AppCompatActivity {

    int pokeID;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_poke_details);

        Intent j = getIntent();
        pokeID = j.getExtras().getInt("id");

        getActionBar();

        Button back = (Button)findViewById(R.id.back);

        back.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent i = new Intent (getApplicationContext(), PokemonDetails.class);
                i.putExtra("id", pokeID);
                startActivity(i);
            }
        });

    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();
        Intent i = new Intent (getApplicationContext(), PokemonDetails.class);
        i.putExtra("id", pokeID);
        startActivity(i);
    }
}

The back arrow on the ActionBar or Toolbar is the HomeAsUp button and is handled in onOptionsItemSelected().

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return true;
    }
    return super.onOptionsItemSelected(item);
}
