无法使用节点js将数据记录到数据库表中

Question

DatabaseConnection.prototype.add_user_transaction =function(tournamenId,userId, callback ){

     var dbConn = this;

     var insertObject = {
        //data
        };
     var ticketModel = dbConn.rummyConnection.model('tournament_user_transactions');
     var transactionPromise = ticketModel.update(insertObject ,{where: {tournament_id: tournamenId, user_Id: userId}}).then(function(result) {
        callback({status:"SUCCESS", result: result});
     }).catch(function(err){

        debug(err.stack);
        var error = new Error('Error ');
        callback({status:"ERROR", error:error});
     });
};



// On debug result is[0], record is not inserting into table.
