Passing Input while creating Angular 2 Component dynamically using ComponentResolver

You have to pass it imperatively like:

loadChild(): void {
  this._cr.resolveComponent(Child1Component).then(cmpFactory => {               
    let cmpRef = this.childContainer.createComponent(cmpFactory);
     cmpRef.instance.var1 = someValue;  
   });
 }

also similar with registering handlers for outputs.

loadChild(): void {
  this._cr.resolveComponent(Child1Component).then(cmpFactory => {                
    let instance: any = this.childContainer.createComponent(cmpFactory).instance;
    if (!!instance.close) {
      // close is eventemitter decorated with @output 
      instance.close.subscribe(this.close);
    }
  });
}

close = (): void => {
  // do cleanup stuff..
  this.childContainer.clear();
}
