How to use the schema-based-json-editor.toNumber function in schema-based-json-editor

updateSelection(value: any) {
    this.value = this.schema.type === 'integer' ? common.toInteger(value) : common.toNumber(value)
    this.validate()
    this.updateValue.emit({ value: this.value, isValid: !this.errorMessage })
  }
  trackByFunction = (index: number) => {

onChange(e: { target: { value: string } }) {
    this.value = this.schema.type === 'integer' ? common.toInteger(e.target.value) : common.toNumber(e.target.value)
    this.validate()
    this.$emit('update-value', { value: this.value, isValid: !this.errorMessage })
  }

private onChange = (e: React.FormEvent<{ value: string }>) => {
    this.value = this.props.schema.type === 'integer' ? common.toInteger(e.currentTarget.value) : common.toNumber(e.currentTarget.value)
    this.validate()
    this.setState({ value: this.value })
    this.props.updateValue(this.value, !this.errorMessage)
  }
  private validate() {
