Can't make button react to onClick

Question

I have these 2 buttons inside an Activity. The backBtn works fine, but nothing happens when I click on the reg_country button. Any idea of what's going on?

[EDIT] Edited with some log, onClick just does't executes when I touch the button.

 08-10 09:33:08.608: D/dalvikvm(806): GC_EXTERNAL_ALLOC freed 365 objects / 24360 bytes in 58ms
 08-10 09:33:11.608: E/RegisterActivity(806): Activity started
 08-10 09:33:14.317: E/RegisterActivity(806): onClick (backBtn)
 08-10 09:33:16.268: E/RegisterActivity(806): Activity started

Part of the Activity code

Log.e("RegisterActivity", "Activity started");

backBtn = (Button) findViewById(R.id.backBtn);
backBtn.setText("Cancelar");
backBtn.setVisibility(View.VISIBLE);

backBtn.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Log.e("RegisterActivity", "onClick (backBtn)");
        finish();
    }
});


reg_country = (Button) findViewById(R.id.reg_country);
reg_country.setText("reg_country");
reg_country.setClickable(true);
reg_country.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        Log.e("RegisterActivity", "onClick (reg_country)");
        finish();
    }
});

Maybe because reg_country stays inside a TableLayout? backBtn comes from the included actionbar_layout
