OnCreate() не вызывается getWritableDatabase()

Я пишу базу данных в своем приложении для Android, но мои таблицы не создаются. Я добавил точки останова в мой метод onCreate, и вызывается моя getWriteableDatabase и getWritableDatabase, но onCreate не является.

package com.fslade.app;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
import android.util.Log;

public class DatabaseHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "applicationdata";
    private static final int DATABASE_VERSION = 1;
    public static final String DATABASE_TABLE = "peopleT";

    // Database creation sql statement
    private static final String DATABASE_CREATE = "create table " + DATABASE_TABLE + " (_id integer primary key autoincrement, "
            + "company_name text not null, name text not null, city text not null, vertical text not null, title text not null, email text not null, bio text not null, photo text not null, status text not null);";

    public DatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Method is called during creation of the database
    @Override
    public void onCreate(SQLiteDatabase database) {
        database.execSQL(DATABASE_CREATE);
    }

    // Method is called during an upgrade of the database, e.g. if you increase
    // the database version
    @Override
    public void onUpgrade(SQLiteDatabase database, int oldVersion,
            int newVersion) {
        Log.w(DatabaseHelper.class.getName(),
                "Upgrading database from version " + oldVersion + " to "
                        + newVersion + ", which will destroy all old data");
        database.execSQL("DROP TABLE IF EXISTS todo");
        onCreate(database);
    }
}

И в моей базе данных я вызываю getWriteableDatabse():

package com.fslade.app;

import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;

    public static final String KEY_ID = "_id";
    public static final String KEY_COMPANY_NAME = "company_name";
    public static final String KEY_PERSON_NAME = "name";
    public static final String KEY_CITY = "city";
    public static final String KEY_VERTICAL = "vertical";
    public static final String KEY_TITLE = "title";
    public static final String KEY_EMAIL = "email";
    public static final String KEY_BIO = "bio";
    public static final String KEY_PHOTO = "photo";
    public static final String KEY_STATUS = "status";

    private static final String[] COLUMNS = { KEY_ID, KEY_COMPANY_NAME,
            KEY_PERSON_NAME, KEY_CITY, KEY_VERTICAL, KEY_TITLE, KEY_EMAIL,
            KEY_BIO, KEY_PHOTO, KEY_STATUS };

    private Context context;
    private SQLiteDatabase database;
    private DatabaseHelper dbHelper;

    public ContentStorageHelper(Context context) {
        this.context = context;
    }

    public ContentStorageHelper open() throws SQLException {
        dbHelper = new DatabaseHelper(context);
        database = dbHelper.getWritableDatabase();
        // dbHelper.onCreate(database);
// I added this onCreate() to see if it helped, but when I ran it
// it said that the database had already been created
        return this;
    }

    public void close() {
        dbHelper.close();
    }
