How to use output parameter of Stored Procedure using Datalayer.SP element

We have written the custom logic for server side pagination. For this we have written two stored procedures viz one for getting the total number of records and another for getting the actual records.

Now we want to merge both Stored procedures together and use Output parameter to return the count.

We have also modified the SP accordingly to use output parameter.

Following are the changes we did at logi level to get the total number of records through output parameter but it is not working. Are there anything we missing to implement?

Above Method does not return any record data. Please let us know how we can achieve this.
