FormView.DataBind with Jquery

I have a called FormView frmcontrato, I want that after click of btnstatus saw jquery it makes the update of the ones of the data of the FormView with the DataBind. What I am ordering in $.post is for making a Update in the data base.

$('#btnstatus').click(function () {
  event.preventDefault();
  $.post('xcrud.aspx?acao=mudastatus&t=contratos&s=<%# Eval("status")%>&codigo=<%# Eval("codigo")%>');<%frmContrato.DataBind()%>;
}); //Click

I tried to use

<%frmContrato.DataBind()%>;

 thus but it did not function.
