Discord.js interaction won't update

I have a message with 3 buttons and I want to disable all 3 of the buttons after they have been clicked.

handle: async function(interaction) {
 interaction.deferUpdate();
 let components = interaction.message.components[0].components.forEach(c => {
 c.setDisabled(true)
 })
 await interaction.message.edit({embeds: interaction.message.embeds, components: components})
 // Do some other stuff
}
I have tried it with 

interaction.update()

and multiple other ways but i can't get it to work.

Solution of the problem

After you deferred your reply with .deferReply() or .deferUpdate() you need to use .editReply()

Code @ discordjs.guide

collector.on('collect', async i => {
 if (i.customId === 'primary') {
 await i.deferUpdate();
 await wait(4000);
 await i.editReply({ content: 'A button was clicked!', components: [] });
 }
});
