setOnCheckedChangeListener does not work (no crash)

Hi guys I'm trying to set an OnCheckedChangeListener on a checkbox.

Here the code of the checkbox:

<CheckBox
    android:id="@+id/checkBox1"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:layout_gravity="center_vertical"
    android:text="" />

Here the code of the event listener:

checkbox_task.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
            adapter.notifyDataSetChanged();
        }
    });

The checkbox is in a different layout than the main xml but I think I take it in the correct way:

taskView = getActivity().getLayoutInflater().inflate(R.layout.item_todo, null);

checkbox_task = (CheckBox) taskView.findViewById(R.id.checkBox1);

The strange thing is that the application does not crash and also the debug does not never pass through setOnChangeListener and i don't know why.

Someone can help me? Thank you all
