Clear interval not working ionic2

Every variation of clearinterval doesn’t work…
I have timer scripts on one tab, that shouldn’t work on another tab… don’t know why thats
not build in

here’s my code

           this.home_game_timer = setInterval(()=>{

                var link = '****';
                var data = JSON.stringify({,uid:this.uid});
                let headers = new Headers({ 'Content-Type' : 'application/x-www-form-urlencoded; charset=UTF-8' });
                let options = new RequestOptions({ headers: headers });
                return, data,options)
                //print php error
                //.subscribe(data => {console.log(data._body)})
                 //get json response
                  .map(data => data.json())
                  .subscribe((data) =>{
                    this.timer_data = data,
                    this.list_players = data
                    console.log("home ts 164" +JSON.stringify(this.timer_data))

          ionViewWillLeave() {

Did you try to put the NgZone inside the Interval ?
