Toolbar hamburger interfering with back arrow button

I'm seting a drawer with an hamburger, when I open a fragment I want to remove the hamburger and replace it with an arrow that calls onBackPressed().

What's happening is the hamburger gets replaced by the arrow, but the listener on the arrow doesn't get called. If I remove the ActionBarDrawerToggle completely it will work. How can I fix this?

Opening the new fragment:

    Fragment_Subjects frag = new Fragment_Subjects();
    fm.beginTransaction()
            .replace(R.id.mainContainer, frag)
            .addToBackStack(null)
            .commit();
    toggle.setDrawerIndicatorEnabled(false);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);

Seting the drawer toggle:

    drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    toggle = new ActionBarDrawerToggle(this, drawer, mToolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); //back arrow works when this line is removed
    assert drawer != null;
    drawer.setDrawerListener(toggle);
    toggle.syncState();

Back arrow listener:

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

onBackPressed:

@Override
public void onBackPressed() {

    if(drawer.isDrawerOpen(Gravity.START)){
        drawer.closeDrawer(Gravity.START);
    }else{
        super.onBackPressed();
    }
}

Try this: 

 toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
              onBackPressed();
        }
 });
