无法通过字体真棒标签使单选按钮在ng-repeat中工作

Question

I am struggling with getting some Font Awesome labels to work with radio buttons in an AngularJS ng-repeat. I know there is an issue with the $scope inside ng-repeat, and I have copied the examples of several work-arounds that mentioned using $parent , but none of the fixes have seemed to work for me thus far. I want row clicking to still toggle the radio buttons as well.

HTML

<div ng-app>
    <div ng-controller="TodoCtrl">
        <div class="container-fluid">
            <div class="row" ng-repeat="i in integrations" ng-click="$parent.isChecked = !$parent.isChecked">
                <div class="col-xs-1">
                    <input id="int{{$index}}" type="radio" ng-model="$parent.isChecked" name="radiointegration" ng-value="i.isChecked" />
                    <label for="int{{$index}}"></label>
                </div>
                <div class="col-xs-6" style="padding-top:10px">{{i.text}}</div>
                <div class="col-xs-5" style="padding-top:10px">{{i.isChecked}}</div>
            </div>
        </div>
    </div>
</div>

JS

function TodoCtrl($scope) {
    $scope.integrations = [{
        text: 'one',
        isChecked: false
    }, {
        text: 'one',
        isChecked: false
    }, {
        text: 'one',
        isChecked: false
    }, {
        text: 'one',
        isChecked: false
    }, {
        text: 'one',
        isChecked: false
    }];
}

CSS

.row:nth-of-type(even) {
    background: #f3f8fe;
}
input[type=radio] {
    display: none;
}
/* to hide the radio itself */

input[type=radio] + label:before {
    font-family: FontAwesome;
    display: inline-block;
}
input[type=radio] + label:before {
    content: "\f1db";
}
/* unchecked icon */

input[type=radio] + label:before {
    letter-spacing: 10px;
}
/* space between radio and label */

input[type=radio]:checked + label:before {
    content: "\f00c";
    color: $harmonyColorGood
}
/* checked icon */

input[type=radio]:checked + label:before {
    letter-spacing: 5px;
}
/* allow space for check mark */

label {
    margin-top: 7px;
    margin-left: 10px;
    font-size: 25px;
}
label:hover,
.row:hover {
    cursor: pointer;
    background: #f5f5f5;
}

Somehow you handled your radio buttons like checkboxes.

I've removed some unnecessary variables in your fiddle, please check if this is the effect you need?

<div class="row" ng-repeat="i in integrations">
    <div class="col-xs-1">
        <input id="int{{$index}}" type="radio" ng-model="$parent.checked" name="radiointegration" ng-value="i.text" />
        <label for="int{{$index}}"></label>
