#TESTE 1: assim funciona .then((result:any)=>{

this.userProvider.createAccount(this.model.email, this.model.password).then((result:any)=>{
  this.toast.create({ message: 'sucesso. Token: ' + result.token, position: 'bottom', duration: 2000 }).present();
}).catch( );



#TESTE 2: usando funcao anonima ao inves de arrow function nao funciona .then(function(result:any) {

this.userProvider.createAccount(this.model.email, this.model.password).then(function(result:any) {
  this.toast.create({ message: 'sucesso. Token: ' + result.token, position: 'bottom', duration: 2000 }).present();
}).catch( );

#TESTE 3: mas, assim funciona
let test = this.toast.create({ message: 'sucesso. Token: ?', position: 'bottom', duration: 2000 });

this.userProvider.createAccount(this.model.email, this.model.password).then(function(result:any) {
  test.present();
}).catch( );
