Ajax.BeginForm returning PartialView as View

Good Night!
I'm working on a Bed Management project. In a given View, I am displaying the Registered Nurses, and for filtering purposes , a field where you can search for the name of the Department to which the ward ( s) belongs.
As pictured below:

Forthat,I'musingtheajaxHelperAjax.BeginFormtoreturnaPartialViewandpopulatethetable.TheproblemisthatI'mgettingaseparateviewwithonlythedata.Ialreadyresearchedhereonthesite,somepeoplehadthesameproblemandincludedUnobtrusivein_Layout,butIalreadydidthat.Ihavecheckedeverythingseveraltimes,andIcannotidentifywhatishappening.

• Web.configisalreadysettoUnobtrusiveforTrue
• I'vealreadyincludedthepackagevalidate.Unobtrusive
• AsDefault_LayoutdoesnotloadUnobtrusive,Ialreadydidthisfix.
• MycontrollerhasActionPartialViewResult

InNursingControllerIhave:

[HttpPost][ValidateAntiForgeryToken]publicPartialViewResultIndexDep(stringpesquisa){returnPartialView((_enfermariaAppService.ObterPeloNomeDoDepartamento(pesquisa)));}

IntheIndex(theimageabove)Ihavethefollowingcode:

//AjaxOptions@{varajaxOpts=newAjaxOptions{UpdateTargetId="tbBody",
        HttpMethod = "Post",    
    };
}
//Formulário 
@using (Ajax.BeginForm("IndexDep", ajaxOpts))
{
   @Html.AntiForgeryToken()
   <div class="form-inline">
       @Html.TextBox("pesquisa","", new { @class = "form-control", @placeholder="Pesquise pela sigla do departamento" })
       <input type="submit" value="Pesquisar" class="btn btn-info" />
   </div>      
}
//Tabela onde deveria ser repassado a partialView
<table class="table table-bordered">
    <thead>
        //Cabeçalhos...
    </thead>
    <tbody id="tbBody">
        //Linhas...
    </tbody>

From now on, I thank you immensely for all of you who can collaborate. Thanks.
