android: Kill and Activity onClick

In my android app i am launching an activity using Intent. this activity uses a different layout which has a close ImageButton. I want to set the onClick event to close this activity and go back to the previous activity. i am using the finish() method to achieve this but nothing happens when i click on the close Image Button.

Following is the Code i am using:

To Launch the Activity:

public void stOn(){
    Button sb = (Button)findViewById(R.id.sb);
    sb.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v){
            Intent scIntent = new Intent(MainActivity.this, St.class);
            MainActivity.this.startActivity(scIntent);
        }
    });
}

And to Destroy the Activity:

public void stOff(){
    ImageButton pw = (ImageButton)findViewById(R.id.pw);
    pw.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View v){
            finish(); // Finish Current Activity
        }
    });
}

What am i doing wrong ?

As Kurosawa Hiroyuki say in comment your function stOff() is maybe not called.

That's maybe something you already done but, more generally, in Android, we use to declare all the interface elements (Button, ImageButton, EditText, ...) as fields of the activity and applying findViewById() and setOnClickListener(...) functions inside the onCreate(Bundle savedInstanceState) function.
