Calling a function of UI Action into UI page

[labandar]

Hello everyone, I'm currently working on Change module. For a specific requirement I need to call a method of 'Request Approval' UI Action [onAssess] into a UI Page to do come Calculation. The method I need to call from the UI Action is 

invokeRiskAssessment() the action name of the UI Action is 'state_model_request_assess_approval' it's on click method is moveToAssess();

Firstly is it possible to call an UI Action method into the client script of UI page? If possible can someone help me out here.
