Cell is not recalculated after setting value in dependent cell

I have this simple code:

excel = ExcelCompiler(filename=fname)

excel.evaluate('TEMP!C2')       # touch to be able to set
excel.set_value('TEMP!C2', 'SOMEVALUE')

print(excel.evaluate('TEMP!C2'))
print(excel.evaluate('TEMP!EN2'))

Cell EN2 has a CONCATENATE formula with C2 and some fixed cells. Problem is that is never recalcs the formula after setting the C2 value.
