Enhancing leaflet popup functionality by incorporating ng-click into the onEachFeature function

After creating a map and connecting it with my geojson api, I encountered an issue when trying to link each marker popup with ng-click. Simply adding HTML like this did not work as expected:

layer.bindPopup("<button ng-click='()'>+feature.properties.title+</button>");

This problem led me to create the following code snippet. Unfortunately, I received an error message stating "Error: [ng:areq] Argument 'scope' is required."

$http.get("http://markers.json").success(function(data, status) {
angular.extend($scope, {
geojson: {
 data: data,
 onEachFeature: function(feature, layer, scope) {
   var template = "<button class='button button-clear button-royal' ng-click='aa()')>" +feature.properties.title +"</button>";
   var linkFn = $compile(template);
   var content = linkFn(scope);
   layer.bindPopup(content);
 },
}
});
});

As a newcomer to Angular and JavaScript, I believe there might be something obvious or silly causing this issue. Any assistance would be greatly appreciated. Thank you!

When utilizing the onEachFeature method, there is no necessity to include scope as a parameter. The scope is automatically accessible via the variable $scope:

$http.get("http://markers.json").success(function(data, status) {
    angular.extend($scope, {
        geojson: {
            data: data,
            onEachFeature: function(feature, layer) {
                var template = "<button class='button button-clear button-small button-royal' ng-click='aa()'>" +feature.properties.title +"</button>";
                var linkFn = $compile(template);
                var content = linkFn($scope);
                layer.bindPopup(content[0]);
            }
        }
    });
});
