Schematic cdf value not displaying correctly

I have a script that sets the cdf value of a schematic symbol but it does not display the value correctly in the schematic cellview. When I look at the value from the property menu the values are correct. I have to toggle the variable on the property menu nil and back to t then values will display in the cellview correctly.

 Is there a callback the property menu does when you hit apply/OK that I need to add the script. Or am I missing something in the script to update the schematic cellview.

Some different examples I am trying:

procedure(stdLib_getPcellCdf(obj var)
let(    (cdfVal)
foreach(cdf cdfGetInstCDF(obj)~>parameters
        if(equal(var cdf~>name) cdfVal = cdf))
cdfVal
); end of let
); end of stdLib_getPcellCdf

procedure(stdLib_setPcellCdf(obj var val) stdLib_getPcellCdf(obj var)~>value = val )

procedure(chngSymVal(cv)

foreach(a cv~>instances

cd=cdfGetInstCDF(a)

foreach(param cd~>parameters
if(equal("multidesign" param~>name) then param~>value=t hiFlush() )

))

schCheck(cv)

dbSave(cv)

)
