I don't know if this might answer your question but you can send context or methods of parent class to child class and then access functions or methods of parent class in child component thereby having a sort of two way binding.This might not be the right way to do it but it works most of the times when you need to manipulate parents data from children. Ex: In the render of parent class you can call child component like this:
<ChildClassName parentContext={this} />
Now if you would like to manipulate some handler of parent class you can do in this manner:
this.props.parentContext.handlerFunction(parameters);
where handlerFunction is defined in parent class.
Again it is strongly advisable not to do this kind of things in react but sometimes it makes your work quite easier.
Always use flux or flux-style modules like redux or mobx to handle data flow as they make task of modularizing and managing data flow quite easier.
