Why is the on event not firing on the vue component?

Question

Web development

in the component I cling to the created hook, it emits normally. The server also accepts all the rules. Only now, when the server itself emits a message, the view does not want to accept it, as if it did not subscribe.
socket is defined globally, outside the vue instance

created: function() {
  socket.on('listfromserver',function(e) {
    alert('any data');
  });
  socket.emit('list','get');						
},

Answer 1

Someone, shoot him...
But seriously, tell me the difference between responsive and adaptive in your view?
In order not to be considered a flood: bootstrap.

Answer 2

socket.emit('listfromserver','get');
