asp.net mvc 4 - Ajax.beginform only shows Partial View MVC4 -

when call beginform ajax function, access partialview instead of placing in target refreshs whole view placing code of partialview executed.

these scripts:

 bundles.add(new scriptbundle("~/bundles/superbundle").include(         "~/scripts/jquery-{version}.js",         "~/scripts/jquery-ui-{version}.js",         "~/scripts/jquery.unobtrusive*",         "~/scripts/jquery.validate*",         "~/scripts/jquery.unobtrusive-ajax.js")); 

this partialview _busquedadesensores.cshtml

@model ienumerable< recnons.models.getsensorbyclient_result>       @using (ajax.beginform("entradasalida", "home", new ajaxoptions { insertionmode = insertionmode.replace, httpmethod = "post",  updatetargetid = "entradasalida" }))     {      <select id="sensores" name="sensores">        @foreach (var item in model)        {        <option value="@item.id">@item.id</option>         }         </select>        <input type="submit" value="submit" />     } 

this homecontroller

    [httppost]     public actionresult busquedadesensores(int identificador)     {         viewbag.message = "siga los pasos para completar el proceso...";         retail2entities cl = new retail2entities();          list<getsensorbyclient_result> sensores = cl.getsensorbyclient(identificador,0).tolist();         return partialview("_busquedadesensores",sensores);      } 

finally here part of index try use ajax function

<ol class="round">     <li class="one">      @using (ajax.beginform("busquedadesensores", "home", new ajaxoptions { insertionmode = insertionmode.replace, httpmethod = "post", updatetargetid = "busquedadesensores" }))     {         <select id="identificador" name="identificador">        @foreach (var item in model)        {        <option value="@item.idclient">@item.name</option>         }         </select>        <input type="submit" value="submit" />       }      </li>      <li id="busquedadesensores "class="two">      </li>      <li id="entradasalida "class="three">      </li> </ol>
