this is unavailable in that method.. when you call this.changeContent on line 60 change it to this.changeContent.bind(this). That will bind your component instance to the method.

you can also do this in a constructor if you want to by adding: this.changeContent = this.changeContent.bind(this) inside the constructor below super(props), then you can use the method as you have it
