Angular2 boolean md-radio-button not working

I need two radio buttons to check between two options. I used following.

<md-radio-button [value]=true [(ngModel)]="carSelected" name="carOption">Car</md-radio-button>
<md-radio-button [value]=false [(ngModel)]="carSelected" name="busOption">Bus</md-radio-button>

In my component, I have carSelected boolean variable

public carSelected: boolean = true;

But, the radio buttons won't get updated with the value of carSelected. Also, when radio buttons are checked, carSelected doesn't get updated either.

What could be going wrong here?

Try this. This works for me. There is a method that we can trigger in changes.you can pass the value you need using that.

  <md-radio-group class="example-radio-group" [(ngModel)]="carSelected">
    <md-radio-button [value]=true (change)="getval('car')">Car</md-radio-button>
    <md-radio-button [value]=false (change)="getval('Bus')">Bus</md-radio-button>
  </md-radio-group>

My TS File

getval(car){
  this.carSelected=true;
  console.log(car)
}

read the API reference here. you can do lot more with angular material 2.

If you need more features that material haven't .use this UI platform.

Try this In Html:

<md-radio-group [(ngModel)]="carSelected">
  <md-radio-button [value]=true name="carOption">Car</md-radio-button>
  <md-radio-button [value]=false name="busOption">Bus</md-radio-button>
</md-radio-group>

In component: public carSelected: boolean = true;

first of all radio buttons required same names to work as radio buttons. everything else is fine in your code.

you should bind ngModel to the <md-radio-group> tag not to <md-radio-button> tag.

and here is the link that shows how to handle different form controls in angular 2

i hope this will help.
