Modify endpoint ReaderQuotas programmatically

I have a dynamic client to a service. How can i change the ReaderQuotas property of it's endpoint binding?

I tried like this but it doesn't work ...

 DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);

 foreach (ServiceEndpoint endpoint in factory.Endpoints)
 {
     Binding binding =  endpoint.Binding;

     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxArrayLength = 2147483647
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxBytesPerRead =2147483647;
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxDepth = 2147483647;
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxNameTableCharCount = 2147483647;
     binding.GetProperty<XmlDictionaryReaderQuotas>(new BindingParameterCollection()).MaxStringContentLength = 2147483647;
   }

Even after doing this the ReaderQuotas values remain the default ones.

I also tried like this and still doesn't work:

     DynamicProxyFactory factory = new DynamicProxyFactory(m_serviceWsdlUri);

     foreach (ServiceEndpoint endpoint in factory.Endpoints)
     {
         System.ServiceModel.Channels.BindingElementCollection bec = endpoint.Binding.CreateBindingElements();

         System.ServiceModel.Channels.TransportBindingElement tbe = bec.Find<System.ServiceModel.Channels.TransportBindingElement>();

         tbe.MaxReceivedMessageSize = 2147483647;
         tbe.MaxBufferPoolSize = 2147483647;
         TextMessageEncodingBindingElement textBE = bec.Find<TextMessageEncodingBindingElement>();

         if (textBE != null)
         {

             textBE.ReaderQuotas.MaxStringContentLength = 2147483647;
             textBE.ReaderQuotas.MaxArrayLength = 2147483647;
             textBE.ReaderQuotas.MaxBytesPerRead = 2147483647;
             textBE.ReaderQuota
