I just checked the dragon test on my vtk master build and it worked fine. I started steamvr first then I ran it as
C:\Users\ken.martin\Documents\vtk\bin>bin\vtkRenderingOpenVRCxxTests.exe “TestDragon” “-D” “C:/Users/ken.martin/Documents/vtk/bin/ExternalData/Testing” “-T” “C:/Users/ken.martin/Documents/vtk/bin/Testing/Temporary” -I
Not sure what is off on your example but if you can get the dragon test working maybe that will give you a reference. You might need to copy the controller files into your bin directory. e.g.
