Cannot get values to store in SQLite Android

So I have the following pieces of code and I can't seem to get my application to store any information in the SQLite Database, Any help will be appreciated! Below is my database handler.

        public void insertRec(HashMap<String, String> queryValues) {
            SQLiteDatabase database = this.getWritableDatabase();
            ContentValues values = new ContentValues();
            values.put("regNo", queryValues.get("regNo"));
            values.put("carMake", queryValues.get("carMake"));
            values.put("carModel", queryValues.get("carModel"));
            database.insert("recs", null, values);
            database.close();
        }
}

Here is the button code I use to add a new record.

 public class Record extends Activity implements OnClickListener{

        public void onClick(View view) {

            HashMap<String, String> queryValues = new HashMap<String, String>();
            queryValues.put("regNo", regNo.getText().toString());
            queryValues.put("carMake", carMake.getText().toString());
            queryValues.put("carModel", carModel.getText().toString());
            controller.insertRec(queryValues);
