如何从数据服务器中选择单选按钮？

Question

任何人都可以帮助我将服务器上的数据绑定到我选择的单选框，这里是我的radioview.component.html来查看从服务器数据中选择的广播：

<StackLayout>
  <Label text="Tipe :" paddingLeft="10" textWrap="true" row="0" col="0"></Label>
  <StackLayout *ngFor="let option of radioOptions" class="inline">
    <StackLayout orientation="horizontal" verticalAlignment="center" >
      <CheckBox #elem [checked]="option.selected" (checkedChange)="elem.checked !== option.selected && changeCheckedRadio(option)" class="checkbox" boxType="circle"></CheckBox>
      <StackLayout verticalAlignment="center">
        <Label [text]="option.text" textWrap="true" (tap)="changeCheckedRadio(option)"></Label>
      </StackLayout>
    </StackLayout>
  </StackLayout>
</StackLayout>

这是我的 radioview.component.ts

import { Component, OnInit } from '@angular/core';
import { Switch } from "ui/switch";
class RadioOption {
  text: string;
  selected: boolean = false;
  value:string;
  constructor(text: string, value: string) {
    this.text = text;
    this.value = value;
  }
}
@Component({
    moduleId    : module.id,
    selector    : 'warehouse-detail',
    providers   : [httpService]
})
export class RadioViewComponent {
    valueSelect:string = 2;
    constructor(){
      this.radioOptions = [
        new RadioOption("text one", "1"),
        new RadioOption("text two", "2"),
        new RadioOption("text three", "3")
      ];
    }
  changeCheckedRadio(radioOption: RadioOption): void {
    radioOption.selected = !radioOption.selected;

    if (!radioOption.selected) {
      return;
    }
    this.radioOptions.forEach(option => {
      if (option.text !== radioOption.text) {
        option.selected = false;
      }
    });
  }
}

我想在Radioview中选择值，如何绑定数据？ 需要帮助
