How to change font for InfoStaticTextWidget in runtime

Hi,

I have a InfoStaticTextWidget defined like this

InfoStaticTextWidget

        (

            kTP1StaticWidgetID, // WidgetId

            kSysStaticTextPMRsrcId, // RsrcId

            kBindNone, // Frame binding

            Frame(19,30,300,60), // Frame

            kTrue, kTrue, // Visible, Enabled

            kAlignLeft, // Alignment

            kDontEllipsize, kTrue, // Ellipsize style, Convert ampersands

            kTP1StaticTextKey, // Text Control Data

            0, // WidgetId for associated control for shortcut focus

            -1,-1,

     )

Now I want to change the font for this static widget in runtime.

I have added the code below

     IControlView* controlView1 = panelControlData->FindWidget(kTP1StaticWidgetID);

     InterfacePtr<IUIFontSpec> fontSpec(controlView1,UseDefaultIID())

     fontSpec->SetFontID(kPoint20BoldWindowFontId);

But font for this StaticTextWidget is not changing to kPoint20BoldWindowFontId, instead it shows basic font.

Is there anyone who has tried this before.( I am currently using Indesign CC 2014.).
