Simple function to Validate checkboxes in reactJS

I have made a selection limit function which ensures that total checkbox is above min value and under max value, these values were taken from the JSON which the checkboxes are mapped from, now the selection limit works, but I am trying to add validation to show warnings using onblur, but I am not sure how can the same function can be translated into an onblur validation function. for example where if someone unchecks , it shows on the console that you need to select a minimum of 3 until 3 is checked, same logic as selectData().

Function

  selectData(id, event) {
    let isSelected = event.currentTarget.checked;
    if (isSelected) {
      if (this.state.currentData < this.props.max) {
        this.setState({ currentData: this.state.currentData + 1 });
      } else {
        event.preventDefault();
        event.currentTarget.checked = false;
      }
    } else {
      if (this.state.currentData >= this.props.min) {
        this.setState({ currentData: this.state.currentData - 1 });
      } else {
        event.preventDefault();
        event.currentTarget.checked = true;
      }
    }
  }
