Android : Send KeyEvent from EditText

I have tried to send keyevent from EditText. For this I was using InputConnectionWrapper which I had taken from method onCreateInputConnection():

ZanyInputConnection zic;
@Override
public InputConnection onCreateInputConnection(EditorInfo outAttrs) {
    zic = new ZanyInputConnection(super.onCreateInputConnection(outAttrs),
            true);
    return zic;
}

Inside ZanyInputConnection I wrote method which turn on shift:

private class ZanyInputConnection extends InputConnectionWrapper {

    public ZanyInputConnection(InputConnection target, boolean mutable) {
        super(target, mutable);
    }

    public void turnOnShift(){
        long eventTime = SystemClock.uptimeMillis();
        sendKeyEvent(new KeyEvent(eventTime, eventTime,
                KeyEvent.ACTION_DOWN,KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0, KeyCharacterMap.VIRTUAL_KEYBOARD, 0,
                KeyEvent.FLAG_SOFT_KEYBOARD|KeyEvent.FLAG_KEEP_TOUCH_MODE));
         sendKeyEvent(new KeyEvent(eventTime, SystemClock.uptimeMillis(),
                KeyEvent.ACTION_UP, KeyEvent.KEYCODE_SHIFT_LEFT, 0, 0, KeyCharacterMap.VIRTUAL_KEYBOARD, 0,
                KeyEvent.FLAG_SOFT_KEYBOARD|KeyEvent.FLAG_KEEP_TOUCH_MODE));

    }
} 

It called inside onSelectionChange() method:

@Override
public void onSelectionChanged(int selStart, int selEnd) {
    zic.turnOnShoft();
}

But when method called nothing happens.
