select option not working with ng-model in angular 4

I have a select box where I show elements from a list Code Snippet:

export class CreateauctionComponent implements OnInit{

    createAuctionForm: FormGroup;
    test:any = ["cat","dog"];

    constructor(private _formBuilder: FormBuilder,private _categories: UserCategoriesForAuctionService){
        //
    }
}

In HTML rendered as:

<div class="form-col">
    <h5><span style="color:red;">*</span>{{'createAuction.category' | translate}}:</h5>
    <select class="form_cbx long-select" name="" ng-model="test">
        <option  ng-options="t in test">{{t}}</option>
    </select>   
</div>

I am not able to see any values. Only one blank field in the list. Can anyone direct what is the issue here?

It should be,

<select [(ngModel)]="selectedanimal" (ngModelChange)="onChange($event)">
  <option *ngFor="let c of test" [ngValue]="c"> {{c}} </option>
</select>
