Embed message doesn't update

I wonder if your problem is that you're either re-using variable names, putting the old data back into the edited message, or something else. Anyway, here's something that worked for me:

1) Create an Embed to send to the user (I assume you already did this, creating the Embed you showed on imgr):

const embed = new Discord.RichEmbed({
  title: 'Suggestion by someone',
  description: 'This is a test suggestion. Can you please like it or dislike it :)',
  fields: [{
    name: 'Like:',
    value: '<3'
  }]
});

2) Send Embed to your channel (I added some Reactions to it - possibly the same way as you):

// add reaction emojis to message
message.channel.send(embed)
  .then(msg => msg.react('?'))
  .then(mReaction => mReaction.message.react('?'))
  .then(mReaction => {
    // fun stuff here
  })
  .catch(console.log);

3) Create a ReactionCollector inside where I put // fun stuff here (you can use a different reactionFilter and time limit):

const reactionFilter = (reaction, user) => reaction.emoji.name === '?';

// createReactionCollector - responds on each react, AND again at the end.
const collector = mReaction.message
  .createReactionCollector(reactionFilter, {
    time: 15000
  });

// set collector events
collector.on('collect', r => {
  // see step 4
});
// you can put anything you want here
collector.on('end', collected => console.log(`Collected ${collected.size} reactions`));

4) In the 'collect' event (where I put // see step 4), create a new Embed with mostly similar values (or not - you change whatever you want), then put that new Embed back into the original message via .edit(...):

// immutably copy embed's 'Like:' field to new obj
let embedLikeField = Object.assign({}, embed.fields[0]);

// update 'field' with new value - you probably want emojis here
embedLikeField.value = '<3 <3 <3';

// create new embed with old title & description, new field
const newEmbed = new Discord.RichEmbed({
  title: embed.title,
  description: embed.description,
  fields: [embedLikeField]
});

// edit message with new embed
// NOTE: can only edit messages you author
r.message.edit(newEmbed)
  .then(newMsg => console.log(`new embed added`)) // this is not necessary
  .catch(console.log); // useful for catching errors

So the whole thing ends up looking something like this:

const reactionFilter = (reaction, user) => reaction.emoji.name === '?';

const embed = new Discord.RichEmbed({
  title: 'Suggestion by someone',
  description: 'This is a test suggestion. Can you please like it or dislike it :)',
  fields: [{
    name: 'Like:',
    value: '<3'
  }]
});

// add reaction emoji to message
message.channel.send(embed)
  .then(msg => msg.react('?'))
  .then(mReaction => mReaction.message.react('?'))
  .then(mReaction => {
    // createReactionCollector - responds on each react, AND again at the end.
    const collector = mReaction.message
      .createReactionCollector(reactionFilter, {
        time: 15000
      });

    // set collector events
    collector.on('collect', r => {
      // immutably copy embed's Like field to new obj
      let embedLikeField = Object.assign({}, embed.fields[0]);

      // update 'field' with new value
      embedLikeField.value = '<3 <3 <3';

      // create new embed with old title & description, new field
      const newEmbed = new Discord.RichEmbed({
        title: embed.title,
        description: embed.description,
        fields: [embedLikeField]
      });

      // edit message with new embed
      // NOTE: can only edit messages you author
      r.message.edit(newEmbed)
        .then(newMsg => console.log(`new embed added`))
        .catch(console.log);
    });
    collector.on('end', collected => console.log(`Collected ${collected.size} reactions`));
  })
  .catch(console.log);

For my code, edits are only made when the ? emoji is pressed, just for fun. Please let me know if you need help editing the code above. Hope it helps.

Very late answer. But just in case someone finds this. Theres a much shorter way.

And more useful if you have large embeds and don't want to rebuild your whole embed:

message.embeds[0].fields[0] = "Some much like;
message.edit(new Discord.RichEmbed(message.embeds[0]));
