Remove option from dropdown of the inserted record

[Muhamad Tassadaque Zia]

Hi

I have telerik mvc grid with ajax binding.with CRUD operations in popup mode. One of my field in popup is dropdownlist (I am using html.dropdownlist). Now what I want to achieve is to remove the recently inserted row value from grid. I have tried to use the following code but didn't work. 

function onSave(e) {
          var values = e.values;
          month = values.Month;
          $("#Month option[value='" + month + "']").remove();
      }
