To call Parent's method from child, you can pass the reference like this.

Parent Class

 (this.parentReference = ref)}
    parentReference = {this.parentMethod.bind(this)}
/>

parentMethod(data) {

}

Child Class

let data = {
    id: 'xyz',
    name: 'zzz',
};

//This will call the method of parent

this.props.parentReference(data);
