Substitution not working or sending custom data

[isAlmogK]

Issue Summary

I'm trying to use the substitution option with a transactional email template, the email is getting sent but the custom data for the substitution is not.

Here is my code

var helper = require('sendgrid').mail;
    var from_email = new helper.Email(from);
    var to_email = new helper.Email(to);
    var subject = 'New Mentorloop notification';
    var content = new helper.Content('text/html', text);
    var mail = new helper.Mail(from_email, subject, to_email, content);
    mail.setTemplateId("ea4f8a70-f487-49a3-b0ee-60b5848921e8");

    var personalization = new helper.Personalization();
    personalization.addTo( new helper.Email( from ) );
    var substitution = new helper.Substitution("%text%", "Example User");
    personalization.addSubstitution(substitution);
    mail.addPersonalization(personalization);

    var request = sendgrid.emptyRequest({
      method: 'POST',
      path: '/v3/mail/send',
      body: mail.toJSON()
    });

    sendgrid.API(request, function(error, response) {
      console.log(response.statusCode);
      console.log(response.body);
      console.log(response.headers);
    });

Technical details:

• sendgrid-nodejs Version: lastest version
• Node.js Version: v4.7.0

Got it working, keep this up for anyone else that might run into. I had two issues

1. personalization.addTo( new helper.Email( from ) ); should have been personalization.addTo( new helper.Email(to));

Assigning incorrect email

2. var substitution = new helper.Substitution("%text%", "Example User");

It seems text is already being used
