Angular does not recognize the boolean variable

Within my Angular component, I have declared two boolean variables:

  editingPercent: boolean = true;
  editingCap: boolean = false;

In the corresponding HTML file, there is a checkbox that updates these variables based on user input:

checkedChanged(e) {
    this.editingPercent = !e.value;
    console.log(this.editingPercent);
    this.editingCap = e.value;
    console.log(this.editingCap);
  }

Initially, all seems to be working fine as reflected in the console logs.

However, when attempting to use these variables in a custom validation callback elsewhere in the component:

  capValidation(e) {
    console.log(this.editingCap + ' ' + e.value);
    if (this.editingCap && e.value === undefined) {
      return false;
    }
    else { return true; }
  }

I encounter an issue where this.editingCap is reported as undefined in the console. Why is this happening?

Any insights would be greatly appreciated.

PS: Once this validation callback hurdle is resolved, it can be simplified to just one line of code.

Modify your event handler to use a lambda function

eventHandler = (e) => {
    this.adjustingValue = !e.value;
    console.log(this.adjustingValue);
    this.editingLimit = e.value;
    console.log(this.editingLimit);
}
