I am making an `AJAX` call, and then returning `PartialView` from Controller to populate it in a `div`. 

The following is my code :-

```
var file = document.getElementById("file").files[0];

jq.ajax({
                type: "POST",
                url: '/Main/getData',
                data: formData,
                dataType: 'json',
                contentType: false,
                processData: false,
                success: function (response) {  
                    jq('#partialPlaceHolder').html(response);    
                },
                error: function (error) {
                    alert("Some Error Occured");
                }
            });

 [HttpPost]
        public ActionResult getData(FormCollection form)
        {
            ......

            return PartialView("_pageMain", retMod);
        }

```

As I debug the Code in Controller, there is no Error till the end, But still the AJAX throws the `alert("Some Error Occured")`. 

The PartialView is not populated in div. How to solve this?
