ScriptRegister disabled validation jquery

[bubus]

Good afternoon, I'm working with telerik libraries as libraries add my jquery validationand validation via javascript do not recognize the form.validate, but if I turn off thescriptregister if successfully validated, it is because this behavior or am doing wrong. 

function saveFormDetails(f) {
        var form = $("#testForm");
        //$("#formPlanLabor").validate()
        var sfor = form.serialize();
        form.validate();
        if (form.valid()) {
            var sForm = form.serialize();
            $.post(path + '/PlanLabor/SaveFormDetails/', sForm, function (data) {
                //message.formMessok();
                alert("hola");
            });
        }
        return false;
    }
