No component change for type tagName

[gilsonnetotec]

I need to change the tagName

editor.on('component:update', (component) => {
const classeComponent = component.getClasses()
if (typeTitle != '') {
console.log(typeTitle) // goes into h2
if (classeComponent != '') {
component.set('tagName', typeTitle) // No to changes
component.save() // No to save
}
console.log(component.get('tagName')) // continue h1
}
})
