I have a class Tv with some variables, which are string.
On the page I have DropDown list. I need user to select option from DropDown list and enter the value. And this value must be saved to Tv class variable, which has name like selected string.
Later I pass Tv object to my BackEnd.

My Tv class

export class Tv 
 id: number;
 brand: string;
 model: string;
 color:string;
 display_technology:string;
 screen_size:string;
 refresh_rate:string;
 weight:string;
 condition:string;
 inputs:string;

My DropDown list

<select class="form-control col-md-3">
 <option *ngFor="let param of parameters">param</option>
 </select>
 <div class="col">
 <input type="text" class="form-control" id="paramer" required>
 </div>

UPD Working version.

<div class="row">
 <select name="tvParam" class="form-control col-md-3" [(ngModel)]="selectedParam">
 <option *ngFor="let param of parametrs">param</option>
 </select>
 <div class="col">
 <input type="text" class="form-control" name="tvParamValue" [(ngModel)] = "paramet" (change)="passData()">
 </div>


passData()
 this.tv[this.selectedParam.toLocaleLowerCase()] = this.paramet;
