title: Sequelize JSON data type
body: <p>I have defined a model as </p>
  
  <pre><code>module.exports = function (sequelize, DataTypes) {
    const MyModel = sequelize.define('MyModel', {
      data: {
        type: DataTypes.JSON,
        ...
      },
      ...
    });
  
    return MyModel;
  };
  </code></pre>
  
  <p>I query it using </p>
  
  <pre><code>MyModel.findAll().then(myModels =&gt; ...);
  </code></pre>
  
  <p>However, <code>data</code> field in the query result is a string, not a JSON object. How do I fix it?</p>
