Node.js - can't create table in dynamodb local - aws

I'm using dynamoDB-local with nodejs code.

I have the following code:

var aws = require("aws-sdk")
aws.config.update({"accessKeyId": "aaa",
                   "secretAccessKey": "bbb",
                   "region": "us-east-1"})

var awsdb = new aws.DynamoDB({ endpoint: new aws.Endpoint("http://localhost:8000") });

awsdb.createTable({
  TableName: 'myTbl',
  AttributeDefinitions: [
    { AttributeName: 'aaa', AttributeType: 'S' },
  ],
  KeySchema:[
    { AttributeName: 'aaa', KeyType: 'HASH' }
  ]
}, function() { 
    awsdb.listTables(function(err, data) {
      console.log(data)
  });
});

But it isn't creating the table. I'm getting { TableNames: [] } in logs.
