angular - ng2 update template after making a simple meteor.call -

this has been asked before cannot find answer helps. want oresult change value after call made. answer has appropriate running ng2, meteor , angular-meteor. thanks!

/// <reference path="../../typings/angular2-meteor.d.ts" />  import {input, component, view, ngzone} 'angular2/core'; import {meteorcomponent} 'angular2-meteor';  @component({   selector: 'testcall',   template: `     <button (click)="testcall()">get testcall data</button>     <code><pre>{{oresult}}</pre></code>   ` })  export class testcall extends meteorcomponent {    oresult:any    constructor(private _ngzone: ngzone) {     super();     this.oresult = json.stringify({res: 'start'});   }    testcall(): void {     meteor.call('testcall', function(error,result) {       if (error) {         console.log('failed', error);       } else {           console.log('successful call', result);           this._ngzone.run(() => {               this.oresult = result           });       }     });   } } 

edit

i've shortened code , tried explore if 'this' problem. absence of angular-meteor component makes difference execution of meteor.call. ng2 still fails change template after call has executed. , i've tried , without ngzone. might dump ng2 'cos sure haven't brains or time stuck on trivial stuff this!

this clunky bit of code works fashion. suggest how make meteor.call callback of settimeout?

  testcall(): void {     var self:any =     meteor.call('testcall', (error:any, result:string) => error ?       console.log('failed', error) :       (self.oresult=result, console.log('successful call', self.oresult)));     settimeout(()=>{       this.oresult=self.oresult;     },2000);   } 

export class testcall extends meteorcomponent {    oresult:any    constructor(private zone: ngzone) {     super();     this.oresult = json.stringify({res: 'start'});   }    testcall(): void {     meteor.call('testcall', function(error,result) {       if (error) {         console.log('failed', error);       } else {           console.log('successful call', result);         this.zone.run(() => { // updates within angular zones            this.oresult = result         });       }     });   } }
