View not refresh on browser platform

I have a component on page that user can move. I use hammer pan in a directive that fire events with mouse position. The component subscribe to event and calculate its position with the event.
It works perfectly with ionic serve and in ios platform.
But not on browser platform. When the user try to move component nothing happen (on the screen). The events are fire and kept by the component but the view is not updated. After that if the user clic (anywhere) then the view is updated with the component at the final position.

Is somebody could give me some ways to investigate?
