partial views - Ajax.Beginform refreshing whole page -

-

it redirects whole new page instead of updating current one, have unobtrusive scripts , web.config stuff. why not working?

<div id="preview-image-placeholder"></div>  @foreach (var item in model) {     using (ajax.beginform("previewimage/" + @item.id.tostring(), "music", null, new ajaxoptions { httpmethod = "post", insertionmode = insertionmode.replace, updatetargetid = "preview-image-placeholder" },                                                       new { @enctype = "multipart/form-data", @item.id }))     {         @html.antiforgerytoken()          <input type="file" class="upload-image" id="upload-image-file_@item.id" name="file" accept="image/*">         <button class="btn btn-default" id="btn-preview_@item.id" style="display: none" type="submit"></button>     } } <script src="~/scripts/jquery-1.10.2.min.js"></script> <script src="~/scripts/jquery.unobtrusive-ajax.min.js"></script>

controller:

     [validateantiforgerytoken]      [httppost]         public partialviewresult previewimage(httppostedfilebase file, int id)         {             //do other code stuff                 return partialview("_displayimage", song);         }

_displayimage partial view:

@model ienumerable<musicsite.models.uploadedsong> @using musicsite.customhtmlhelpers;  @foreach(var item in model) {     if (@item.coverimagebytes != null)     {         @html.imagefor(x => item.coverimagebytes, @item.songname + " image", new { @id = "preview-image" })     } }

besides unobtrusive scripts must add microsoft ajax libraries (microsoftajax.js , microsoftmvcajax.js) ajax.beginform works correctly.
