I'm trying to check one from radio buttons in radio list, but without luck.

Could somebody tell me what i'm doing wrong?

Thanks for any help.

I tried to do it by this way:

<div class="list">

      <ion-radio ng-repeat="item in goalTypeList"
                 ng-value="item.value"
                 ng-change="goalTypeChanged(item)"
                 ng-checked="item.selected"
                 ng-model="data.clientSide">
          {{ item.text }}
      </ion-radio>

  </div> 

JS:

.controller('SettingsCtrl', function($scope, $ionicLoading) {

        $scope.goalTypeList = [
            { text: "Dials", value: "dials", selected: true },
            { text: "Conversations", value: "conversations" , selected: false  },
            { text: "Appointments", value: "appointments" , selected: false },
            { text: "Orders", value: "orders", selected: false  }
        ];

        $scope.data = {
            clientSide: 'ng'
        };

        $scope.goalTypeChanged = function(item) {
            console.log("Selected goalType, text:", item.text, "value:", item.value);
        };

It seems that the value of data.clientSide is not in the list goalTypeList. Change the value to match any..

html:

<div class="list">

  <ion-radio ng-repeat="item in goalTypeList"
             ng-value="item.value"
             ng-change="goalTypeChanged(item)"
             ng-checked="item.selected"
             ng-model="data.clientSide">
      {{ item.text }}
  </ion-radio>

js:

  .controller('SettingsCtrl', function($scope, $ionicLoading) {

    $scope.goalTypeList = [
        { text: "Dials", value: "dials", selected: true },
        { text: "Conversations", value: "conversations" , selected: false  },
        { text: "Appointments", value: "appointments" , selected: false },
        { text: "Orders", value: "orders", selected: false  }
    ];

    $scope.data = {
        clientSide: 'appointments'
    };

    $scope.goalTypeChanged = function(item) {
        console.log("Selected goalType, text:", item.text, "value:", item.value);
    };

The value in your $scope.data = { clientSide: 'ng' }; doesn't match any of the values in $scope.goalTypeList.

If the clientSide value on $scope.data was either dials, conversations, appointments or orders then the radio buttons should then load with one of the radio buttons selected.

I hope this helps.

Like @Marc Harry said your ng-value should be equal ng-model. To make it more dynamic (let's say you get an object from the backend and the selected value may change) you could do following:

<div class="list">

      <ion-radio ng-repeat="item in goalTypeList"
                 ng-value="item.value"
                 ng-checked="item.selected"
                 ng-model="data.clientSide">
          {{ item.text }}
      </ion-radio>

</div>

.controller('SettingsCtrl', function($scope, $ionicLoading) {

    $scope.goalTypeList = [
        { text: "Dials", value: "dials", selected: true },
        { text: "Conversations", value: "conversations" , selected: false  },
        { text: "Appointments", value: "appointments" , selected: false },
        { text: "Orders", value: "orders", selected: false  }
    ];

    $scope.data = {
        clientSide: selectedValue()
    };

    function selectedValue = function() {
        for(let i = 0; i < $scope.goalTypeList.length; i++) {
            if ($scope.goalTypeList[i].selected) {
                return $scope.goalTypeList[i].value;
            }
        }
    };

you can use ion-select also with ionChange event:

 <ion-select (ionChange)="checkValue($event)"  interface="popover" 
  placeholder="Select One" >
    <ion-select-option *ngFor="let item of userData" [value]="item"> 
   {{item.optionA}}</ion-select-option>
</ion-select>

In your typeScript:

checkValue(event){ console.log(event.detail.value)}
