why is onCreate never called, even when i call `this.getReadableDatabase();`?

I have created a DB and yet I fail to select a column from it.

android.database.sqlite.SQLiteException: no such column: KEY_PHONE (code 1): , while compiling: SELECT id FROM BLOCKED_PHONES_TABLE WHERE KEY_PHONE = ? AND KEY_IS_BLOCKED = ?

but I did construct such column

my code:

@Override
public void onCreate(SQLiteDatabase db) {
    // SQL statement to create book table

    String CREATE_BLOCKED_PHONES_TABLE = "CREATE TABLE "
            + BLOCKED_PHONES_TABLE + " ( "
            + KEY_ID+" INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_PHONE+" TEXT, "
            + KEY_IS_BLOCKED+" BIT )";

    db.execSQL(CREATE_BLOCKED_PHONES_TABLE);
}



public Phone getItem(String phone) {

    // 1. get reference to readable DB
    SQLiteDatabase db = this.getReadableDatabase();

    Phone result = null;

    Cursor cursor = getReadableDatabase().query(BLOCKED_PHONES_TABLE,
            new String[] { KEY_ID  }, ""+KEY_PHONE+" = ? AND "+KEY_IS_BLOCKED+" = ?",
            new String[] { phone, "1" }, null, null, null);

    // 3. if we got results get the first one
    if (cursor != null) {
        result.id = (cursor.getInt(1));
        result.phone = phone;
        result.isBlocked = false;
    }
    return result;
}

what am i missing?
