$('input[name=cliente]').on('keyup', function(e) {
  // Aqui vou por minhas funções
 }

I usually put in a "off" variable, and "inside" the event I check it out.

var textoCliente = '';
$('input[name=cliente]').on('keyup', function(e) {
    var textoAtualizado = $(this).val();
    if( textoAtualizado != textoCliente ){
        // Aqui vou por minhas funções
    }
    textoCliente = textoAtualizado;
}
