        };
        this.currentPasswordProvided = false;
        this.passwordValidated = false;
        this.completeValidation = false;
        this.emailAddress = '';
        Reset.history = this.props.history;
        this.handleSubmit=this.handleSubmit.bind(this) //<------ Binding it to the class is required because when the submit is clicked, the handler gets unmounted, and this will not be defined in the handleSubmit.
    }
