Unable to get target attributes of material — ui select reaction component

Question

I am trying to get the identifier, name and value from the "Select Field" element of the Material-User Interface component.

This is my container:

//some code is removed to keep things simple
class MyContainer extends Component {

  constructor(props) {
    super(props);
  }

  render() {
    return(
        <MyComp onChange={this._onChange.bind(this)}  />
    );
  }

  _onChange(evt) {
    console.log(evt.target); 
    console.log(evt.target.id);  //blank
    console.log(evt.target.name); //undefined 
    console.log(evt.target.value); //html value of selected option!

  }

 }
 export default connect(select)(MyContainer);

in my presentation component:

  import React, {Component} from 'react';
  import Select from 'material-ui/SelectField';
  import MenuItem from 'material-ui/MenuItem';

  const someData = ["aaaa", "bbbb", "ccccc"];

  class MyComp extends Component {

    render() {
      const {onChange} = this.props;

      return (
        <form >
            <Select
                    value={this.props.test}
                    name={"test"}
                    id={"test"}
                    onChange={this.props.onChange}
                    hintText={"Select a fitch rating service"}>
              {
                someData.map((e) => {
                  return <MenuItem key={Math.random()}  value={e} primaryText={e}/>
                })
              }
            </Select>
        </form>
      );
    }
  }

The problem is that it _onChange(evt)gives the following values:

  evt.id is blank
  evt.name is undefined
  evt.target.value is <div>whatever the selected value was</div> 

It seems that the argument passed is _onChange(evt)not SELECT, but rather an option, as evt.targetit gives when printed <div>whatever the selected value was</div>. who knows why? If I use a simple select (not material-ui) field, then this works as expected (i.e. I can get the identifier, name, correct value of the selected parameter). How to get the target identifier, name..etc from the onChange event of the Material-UI Select component?

P.S _onChange TextField -ui, . :

 _onChange = (event, index, value) => {
    console.log(event.target.id); //blank
    console.log(event.target.name); //undefined
    console.log(index); //correct index
    console.log(value); //correct value
  };

:

material-ui docs, touchtap option, select. , :

onchange :

_onChange(id, name, evt, key, payload) {

  console.log(id);  //id of select
  console.log(name); //name of name
  console.log(payload); //value of selected option
}

select, bind

   <Select
     value={this.props.test}
     name={"test"}
     id={"test"}
     onChange={this.props.onChange.bind(null,"id","name")}
     hintText={"Select a fitch rating service"}>

_onChange = (event, index, value) => {
  e = _.cloneDeep(event); // Here I'm using the cloneDeep method provided by underscore / lodash . User whatever library you prefer. 
  console.log(e.target.id); 
  console.log(e.target.name); 
};

_onChange = (event, index, value) => {
  event.persist() // This stops react from garbage collecting the event object. It may impact performance, but I doubt by much.
  console.log(event.target.id); 
  console.log(event.target.name); 
};

_onChange = (event, index, value) => {
  e = event.native; // This looks the same as a vanilla JS event
  console.log(e.target.id); 
  console.log(e.target.name); 
};
