Ion-range tickers doesn't update with min/max changes

Hello there.
I’m using an ion-range component that it’s min/max values can be changed. when the min/max values are changed the ion-range operate correctly except from re-painting the new ticks to match with the new min/max values.

Here is a sample of the code:
<ion-range [min]=“minVal” [max]=“maxVal” [(ngModel)]=“rangeValue” pin=“true” snaps=“true”></ion-range>

I thought to capture the object and call update, hoping it will “refresh” its internals, but couldn’t find how to do so.

It is a bug ?

Thank you,
