Ionic Framework

I have a input inside an alert, how I can to put autocomplete off?

async promptSave() {
    let igual = 0;
    let alert = await this.alertController.create({
      header: 'Nome da obra',
      inputs: [
        {
          name: 'nome',
          placeholder: 'Introduzir nome',
          //HERE
        }
      ],
      buttons: [
        {
          text: 'Cancelar',
          role: 'cancel'
        },
        {
          text: 'Confirmar',
          handler: data => {
            if(data.nome == ""){
              this.duplicado('O nome da obra deve ser preenchido.');
            }
            else{
              for (let i = 0; i <= this.vet.length - 1; i++) {
                if(data.nome == this.vet[i].nome){
                  igual = 1;
                }
              }
              if(igual == 0){
                this.date = new Date();
                this.formatedDate = this.date.toISOString().substring(0, 10);
                this.a = this.formatedDate.split('-');
                this.b = this.a[2] + "-" + this.a[1] + "-" + this.a[0];

                this.vet.push({
                  'nome': data.nome,
                  'data': this.b
                })

                localStorage.setItem('vetor', JSON.stringify(this.vet));
                localStorage.setItem(data.nome, JSON.stringify(this.juntar));
                this.nome = data.nome;
                this.toastPrompt2();
              }
              else{
                this.duplicado("Nome da obra já existe.");
              }
            }
          }
        }
      ]
    });
    alert.present();
  }
