[jQuery] not work with firefox


Staff the following situation:
<script type="text/javascript">
$().ready(function() {
$("select#tipo").change(function(){
$('div#dinamico_tipo').html('loading...');
$.post('ajax_movimentacao.jsp',
{id: $(this).val() },
function(resposta){
$('div#dinamico_tipo').html(resposta);
}
);
});
});
</script>
Through combo "tipo", I select an option, that sends for the page
ajax_movimentacao.jsp the ID of the selected field, and as return in
div "dinamico_tipo" I receive the changeable "resposta" that is one
input:
<input type="text" id="novo_status" name="novo_status">
This this functioning without problems in the IE and the Firefox. the
problem is when a value in input is passed inserted, and sending way
submit in the form. In the IE the value of the field "novo_status" is
sent normally, but in firefox it does not send the value, passing
blank... what I am making of made a mistake?
