PlotView does not change height with property change

Hello,
I have a PlotView that has the height binds to the property ModelHeight in the view model. The problem is that it does not update after the property change. It only updates when starting up the plotview (the plot view is rendered for the first time) I try PlotModel.InvalidatePlot but it does not work. Seems like the height is fix. 
Does anyone know how to fix this issue?
