/// The primary button control that generates the salary breakdown in a display grid.
/// 1) It checks whether the salary input is not empty, populates a model called initialData with the values associated with the employee.
/// 2) Collects the addition and the deduction components that the user has added from the UI(form) in userAdditionComponents and userDeductionComponents
/// lists respectively and adds them to the initialData model.
/// 3) The SalarySlipProcess() method of FormInput is then invoked to start the salary slip computation process.
/// 4) The computedRules property of initialData model is used to populate the grid shown to the user.
/// 5) The method PopulateGrid() is responsible for filling the display grid with the calculated components (salary Breakdown) that is displayed to the user.
