Add ng-model to checkbox....then iterate data and use delete if it is checked

  $scope.delete = function() {
     angular.forEach($scope.datas, function(val, key) {
       if (val.isclicked) {
         delete $scope.datas[key];
       }
     })
   }

View

<form ng-repeat="data in datas">            
    <input type="checkbox" ng-model="data.isclicked">{{ data.venture }}          
</form>
<button ng-click="delete()">Delete</button>

It is deleting item but not updating the JSON

What do you mean not updating the json? JSON is string data you get from server. $scope.datas has been updated... that's why view changes

To remove from file you need to send data to server and use server code to change file

Suppose, there is a API call /api/delete:id (Where id =1, 2), to delete. Then ?

Assuming you have your data is on the scope, you'd use the JavaScript delete function to remove an item from the array.

So...

delete $scope.data["1"]

Angular's digest should update anything watching that scope property automatically.
