Not able to launch interface in a!statProcess

Hi, 

I am not sure what mistake I am making but, I am trying to launch an interface on icon click which has a!startProcess implemented on it.

Interface Icon SAIL

a!richTextIcon(
                            icon: "info-circle", 
                            caption: local!testVer,
                            link: a!dynamicLink(
                              label: null,
                              value: null,
                              saveInto: {
                                rule!Test_Rule(local!testVer)
                              }
                            )
                          )

Rule Input:

a!startProcess(
  processModel: cons!Test_Const,
  onSuccess: a!save(ri!testData, "Success"),
  onerror: a!save(ri!testData, "Failure")
)

Constant:

And I have one constant "Test_Const" which is calling Process model Of the interface which I am tying to launch

Now, when I click on the icon I get "success" on local!testVar but Interface is not launching.

Please help me on this.
