如何在laravel输入字段中调用AngularJs函数

我有一个HTML表单。我可以用这种形式成功地使用angular js。但是当我使用laravel表单生成器转换表单字段时，我得到了一个错误。

这是我简单的HTML和AngularJs，它工作得很好

var app = angular.module('mainApp', []);
app.controller('availableDay', function($scope) {
  $scope.dayfrom = "";
  $scope.dayto = "";
  $scope.dayfull = function() {
    return $scope.dayfrom + "-" + $scope.dayto;
  }
});

<div class="form-group">
    <div class="row" ng-app="mainApp" ng-controller = "availableDay">
        <div class="col-lg-12">
            <h4 class="page-header">Available in a week</h4>
            <div class="col-lg-6">
                <div class="form-group">
                    <label>Day From</label>
                    <select class="form-control" ng-model = "dayfrom">
                        <option>Monday</option>
                        <option>Tuesday</option>
                        <option>Wednesday</option>
                        <option>Thursday</option>
                        <option>Friday</option>
                        <option>Saturday</option>
                        <option>Sunday</option>
                    </select>
                </div> 
            </div>
            <div class="col-lg-6">
                <div class="form-group">
                    <label>Day To</label>
                    <select class="form-control" ng-model="dayto">
                        <option>Monday</option>
                        <option>Tuesday</option>
                        <option>Wednesday</option>
                        <option>Thursday</option>
                        <option>Friday</option>
                        <option>Saturday</option>
                        <option>Sunday</option>
                    </select>
                </div>
            </div>
            <div class="col-lg-12">
                <div class="form-group">
                    <label>Available Day</label>
                    <input class="form-control" type="text" value="{{dayfull()}}">
                </div>
            </div>
        </div>   
    </div> 
</div>

但是当我要用laravel form builder转换它时，出现了一个错误

语法错误，意外'}'

var app = angular.module('mainApp', []);
        app.controller('availableDay', function($scope) {
            $scope.dayfrom = "";
            $scope.dayto = "";
            $scope.dayfull = function() {
                return $scope.dayfrom + "-" + $scope.dayto;
            }
        });

如何在Laravel表单构建器中使用AngularJs函数{{dayfull()}} ?

{{ Form::text("available_day", '{{'.'dayfull()'.'}}', ["class" => "form-control"]) }}
