Android: Table Row Insert Error. Column does not exist?

So previously I implemented a DB with a table that had 2 columns. I changed my mind and added one more column to the table and tried inserting the new value and I faced this problem even though I correctly (I believe) added all the right column declarations in the classes mentioned below.

TableData Class that contains the column names and data:

public class ImageTableData {

    public ImageTableData()
    {

    }
    public static abstract class ImagesTableData implements BaseColumns
    {
        public static final String ImageID = "imid";
        public static final String PID = "pid";
        public static final String URL = "url";
        public static final String DATABASE_NAME = "jezza_db";
        public static final String TABLE_NAME = "product_pics";
    }
}

And my Query in the DatabaseOperations class:

public String CREATE_IMAGE_QUERY = "CREATE TABLE " + ImagesTableData.TABLE_NAME + " (" + ImagesTableData.ImageID + " VARCHAR, " + ImagesTableData.PID + " VARCHAR, " + ImagesTableData.URL + " VARCHAR);";

And my create query execution:

public void onCreate(SQLiteDatabase db) {
        db.execSQL(CREATE_IMAGE_QUERY);
        }

I believe those are the two declarations. However I started getting THIS error when I added a new column "ImageID". It worked well before when it had only 2 columns.

And my SELECT query crashed as well, returning this error:

12-22 14:13:25.355: E/SQLiteLog(21777): (1) no such column: ImageID
12-22 14:13:25.355: E/DB ERROR(21777): android.database.sqlite.SQLiteException: no such column: ImageID (code 1): , while compiling: SELECT ImageID FROM product_pics WHERE ImageID=imaimablack3jpg

My SELECT Query and code block:

public boolean isImageAdded(DBOps dop, String id)
    {
        try
        {
            String idmod = "ima" + id;
            boolean isAdded = false;
            Log.d("URL Recieved: ", id);
            SQLiteDatabase SQ = dop.getReadableDatabase();
            String sqlQuery = "SELECT ImageID FROM "+ ImagesTableData.TABLE_NAME +" WHERE ImageID="+idmod; 
            Cursor cursor = SQ.rawQuery(sqlQuery, null);
            Log.d("Cursor Count : ", String.valueOf(cursor.getCount()));
            if(cursor.getCount() > 0)
            {
                cursor.close();
                isAdded = true;
            }
            else
            {
                cursor.close();
                isAdded = false;
            }
        }
        catch(Exception ex)
        {
            Log.e("DB ERROR", ex.toString());
        }
        return false;
    }

Why is this happening? I have added the new column correctly havent I? Please help :)
