FormSubmit doesn't update value without refresh page

Hello @Anth0ny24,
When you click Edit button, if you navigate to Edit page and after Submit the button you return to List page. You should use ionViewWillEnter. This function will run functions in it everytime you navigate to List page. If you are at Editing in the Listing page. You should call get data after Editing Submitted.
Basically you should run getdata function after your submission.

ionViewWillEnter() {
    this.getAllData();
  }
