How to catch event on markers just one time

[hoanglethuanthien]

I have task to search some address in one or more than polygon created. So I put function Search in

freeDraw.on('markers', function (event) {

                   if (event.eventType == 'create' && event.latLngs.length > 0) {
                       var coordinates = event.latLngs;
                       var feature = L.polygon(coordinates);
                       $scope.newBounds.extend(feature.getBounds());

                       if ($scope.$parent.SearchSalePropertyModel) {
                           $scope.$parent.SearchSalePropertyModel.Features.push(JSON.stringify(feature.toGeoJSON()));

                       } else {
                           $scope.$parent.SearchLeasePropertyModel.Features.push(JSON.stringify(feature.toGeoJSON()));
                       }

                   } else {
                       return;
                   }
                   $scope.$parent.Search($scope.newBounds);

               });

But the library re-draws all the polygons => make called server twice, how I fix it?
