How to tell rails not to precompile / cache the .js.erb file in my application?

Question

I have a messages.js.erb file in the app / assets / javascripts / channels folder that needs to generate code to select each of the chat rooms and create channel subscriptions for this chat.

Here is my messages.js.erb file

//**app/assets/javascripts/channels/messages.js.erb**

$(document).on('turbolinks:load', function() {
  submitNewMessage();
});

<% Chatroom.all.each do |chatroom| %>
  App['room' + <%=chatroom.id%>] = App.cable.subscriptions.create({channel: 'MessagesChannel', room: <%=chatroom.id%>}, {
  received: function(data) {
   $("[data-chatroom='" + this.chatroomId + "']").removeClass('hidden');
    return $("[data-chatroom='" + this.chatroomId + "']").append(data.message);
  },

  setChatroomId: function(chatroomId) {
    this.chatroomId = chatroomId;
  }
});

<% end %>

function submitNewMessage(){
  //console.log(uid);
  $('textarea#message_content').keydown(function(event) {
    if (event.keyCode === 13) {
        var msg = event.target.value;
        var chatroomId = $("[data-chatroom]").data().chatroom;
        var uid = $('#uid').val();
        //console.log(uid);
        App['room' + chatroomId].setChatroomId(chatroomId);
        App['room' + chatroomId].send({message: msg, chatroom_id: chatroomId, user_id: uid});
        $('[data-textarea="message"]').val(" ");
        return false;
     }
  });
}

Preferably, this file should be reloaded every time a new chat is created, but the rails cache ( precompiling?) the file ( asset?) after the first download and serve it with every request.
