Current behavior:

Note* I am using the videogular2 framework & api to interactive with the ion range component ==> https://github.com/videogular/videogular2

While using the ion range component to scrub through seekbar, range handles do not seek to time when dualKnobs is set to true.

Max range handle properly seeks to time while min range handle remains unresponsive.

Console log shows range values are bond to [(ngModel)] and properly display current range position.

Here is a video showing current behavior ==> https://youtu.be/q7g4W8c2Blk

Expected behavior:

Both range handles should scrub through the seekbar without issue.

Steps to reproduce:

I have created a repo branch for this issue ==> https://github.com/jamesdeantv/ionic-videogular-sample.git
