Default start date on Contract Purchase Agreement page to current date

Business Use Case: When we click on create button on the CPA creation window, the page should open with start date getting defaulted to current date. This I tried achieving through page composer by using the below 4 EL expressions:

#{dateTime.now}
#{oracle.jbo.domain.Date.currentDate}
#{adf.currentDate}
#{generalSettings.formattedCurrentDate}

But none of these expressions returned 'current date' for the field. Please refer the attached document for reference and let us know how we can achieve this.
