Android sql column does not exist

I try to create a table and insert some values but it gives an error and says there is no such kolomn. To me, it looks like I´m creating the table right. What am I doing wrong?

Edit: I changed the code t the code above, but I am still facing the same problem. I commented cv.put(colEnd, "Sales"); and the error is gone. So it seems that the problem is in creating the tabel. Any other ideas?

This is my code:

public class DatabaseHelper extends SQLiteOpenHelper{
static final String dbName="workObjectsDB";
static final String workTable="WorkObjects";
static final String colID="WorkObjectID";
static final String colStart="StartTime";
static final String colEnd="EndTime";

public DatabaseHelper(Context context) {
    super(context, dbName, null,33); 
}

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL("CREATE TABLE "+workTable+" (" +colID+ " INTEGER PRIMARY KEY AUTOINCREMENT , " +colStart+ " TEXT, "+colEnd+ " TEXT)");
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS "+workTable);
    onCreate(db);
}

public void insertSome(){
    SQLiteDatabase db=this.getWritableDatabase();
    ContentValues cv=new ContentValues();

    cv.put(colStart, "Sales");
    cv.put(colEnd, "Sales");
    db.insert(workTable, colID, cv);

    db.close();
}

public Cursor getAll(){
    SQLiteDatabase db=this.getReadableDatabase();
    Cursor cur=db.rawQuery("SELECT * from "+workTable,new String [] {});

    return cur;
}
}

Log:
