Realtime don't work

Real time does not work
When I load my page for the first time the data is loaded but when there is a change on a data, the detection is not triggered.
fireloop version : 1.0.0-beta.2.7

this.realtime.onReady().subscribe(() => {
      this.profileRef = this.realtime.FireLoop.ref<Profile>(Profile);
      this.profileRef
        .on("change", {
          limit: 10,
          order: "id DESC",
          include: "user",
        })
        .subscribe(res => {
          console.log("change...", res);
        });
    });

// method to add new profile
add() {
    const prof: any = {
      type: 1,
      firstName: "xxx",
      lastName: "xxxx",
      phone: 1234567,
    };
    this.profileRef.upsert(prof).subscribe(res => {
      console.log(res);
    });
  }```

The first time i load my page the server :
