Rendering Template apply only on second deploy

SP2013. I have a custom rendering template for a Content Type in CONTROLTEMPLATES folder. Problem is that when I deploy solution by VS on a development machine this template doesn't show up on a form. But after I deploy solution again it shows up. I have following code in FeatureActivated event receiver:

        SPContentType ct = web.ContentTypes["MyContentType"];
        ct.NewFormTemplateName = "NewListForm1";
        ct.EditFormTemplateName = "NewListForm1";
        ct.DisplayFormTemplateName = "DispListForm1";
        ct.Update();

When I check NewFormTemplateName property in PowerShell it has correct value: "NewListForm1" after the first deploy. But rendering template shows only after second deploy.

Now I need to install feature on a production server, but I'm stuck with this problem - no custom rendering tamplate, only default. I've also tried to reactivate feature several times.

Any ideas?
