cannot read property 'Value' of undefined

clearly you are trying to use .Value on something that does have it. e.g. 

this.years.push({'Value': i});
let year = undefined;
year.Value; // BANG

Probably you want something like: 

this.years.push({'Value': i});
let year = this.years[0];
year.Value; // Okay
