  onChange={this.activarBotonEnviar; this.contadorDeCaracteres}
  
  /*This way only execute last function*/
  onChange={this.activarBotonEnviar, this.contadorDeCaracteres}
  
  /*This way only execute last function*/
  onChange={this.activarBotonEnviar} onChange={this.contadorDeCaracteres}
  </code></pre>
