How to update model after changing value of equation?

I am on SolidWoks 2013 SP2.

I have a model with one equation.

"Seal-Dia" = 94

Through API I am setting value of this equation to 80 (EquationMgr.set_Equation()). After that I update model by calling EditRebuild3() from ModelDoc2. Also calling ForceRebulid3() function.

But model is not updating with new equation value.

If I manually open the model and go to equations(Tools->Equations), new equation is already created (both "Seal-Dia" = 94 and "Seal-Dia" = 80 are present). The moment I click on "OK" button, the model is updating with latest equation.
