Android , CheckBox is not clickable

I've got checkBox in my layout. I add it dynamically in the code. Everything looks ok , but checkbox is not clickable. Here's my xml for checkbox :

<CheckBox xmlns:android="http://ift.tt/nIICcg"
    android:id="@+id/pref_calendar_choose_"
    style="@style/PreferencesText"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#00ffffff"
    android:checkMark="?android:attr/listChoiceIndicatorMultiple"
    android:checked="false"
    android:enabled="true"
    android:focusable="false"
    android:focusableInTouchMode="false"
    android:clickable="true"
    android:gravity="center_vertical" />

and here's loop where I'm adding checkboxes :

private void refreshView() {
        String userEmail = PreferencesManager.User.getEmail();
        mCalendarList = CalendarDB.getAll(PreferencesManager.User.getEmail());
        mPrefCalendarChoose.removeAllViews();
        CheckBox checkBox;
        for (int i = 0; i < mCalendarList.size(); i++) {
            checkBox = (CheckBox) getLayoutInflater().inflate(R.layout.item_choose_calendar, null);
            CalendarDB calendarDB = mCalendarList.get(i);
            checkBox.setText(calendarDB.summary);
            checkBox.setId(i);
            checkBox.setOnClickListener(listener);
            if(calendarDB.summary.contains(userEmail)) {
                calendarDB.selected = true;
            }
            else {
                calendarDB.selected = false;
            }
            checkBox.setChecked(calendarDB.selected);
           Log.e(TAG, "refreshView: " + calendarDB.selected );
            if (checkBox.getText() != "") ;
            mPrefCalendarChoose.addView(checkBox);
        }
    }

Everything is set up well but checkbox doesn't react for clicking
