小册子按钮内部标记不起作用

Question

我在显示带有按钮的模态时出现问题，我已将其放在标记消息中，这是我的代码，所有功能都很好，但不是这个按钮， 我的controller.js

 **$ionicModal.fromTemplateUrl('templates/addLocation.html', {
        scope: $scope,
        animation: 'slide-in-up'
      }).then(function(modal) {
          $scope.modal = modal;
        });**


// Get the ouvrage geojson data from a JSON
        $http.get("js/ouvrage/ouvrage.json").success(function(data, status) {
            angular.extend($scope, {
                geojson: {
                    data: data,
                    style: {
                        weight: 2,
                        opacity: 1,
                        color: 'green',
                        dashArray: '3',
                        fillOpacity: 0
                    },

                    onEachFeature: function (feature, layer) {
                    popupOptions = {maxWidth: 350};
                    layer.bindPopup(

                   '<h5><b>Informations sur l"ouvrage : </b></h5>'+
