BCS passing dynamic inputs to methods & calling using in O365

Hi all ,

I have a requirement to pass dynamic values to BDC methods & retrieve data, for this I have created a BDC model file(which has SQL server as external source) with GenericInvoker methods & upload same to Admin central. how do we access these generic methods in Office 365 using JavaScript client object model.

what are the options we have to invoke methods manually by passing dynamic values.

I tried below code. but I getting below error.

The web with URL 'http://XXXXXXXX:26110/sites/RA5' is not an app web. The GetAppBdcCatalog method must be called on an app web.

Any help on this would be appreciated

 function retrieveListItems() {

            // This code runs when the DOM is ready and creates a context object which is needed to use the SharePoint object model
            $(document).ready(function () {
                context = SP.ClientContext.get_current();
                web = context.get_web();
                context.load(web);
                entity = web.getAppBdcCatalog().getEntity("PersonalDetails", "New external content type");
                context.load(entity);
                lob = entity.getLobSystem();
                context.load(lob);
                lobSystemInstances = lob.getLobSystemInstances();
                context.load(lobSystemInstances);
                context.executeQueryAsync(GetLobSubscribesystemInstance, onQueryFailed);
            });

        }



        function Entity() {
            alert("Reached the Entity method");

        }

        //these are the helper methods and variables

        var context;
        var web;
        var user;
        var entity;
        var lob;
        var lobSystemInstance;
        var lobSystemInstances;

        // Initialize the LobSystemInstance.
        function GetLobSubscribesystemInstance() {
            var $$enum_1_0 = lobSystemInstances.getEnumerator();
            while ($$enum_1_0.moveNext()) {
                var instance = $$enum_1_0.get_current();
                lobSystemInstance = instance;
                context.load(lobSystemInstance);
                break;
            }
            context.executeQueryAsync(Entity, onQueryFailed);
        }

    function onQueryFailed(sender, args) {

    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }
