Redirect after Deleting [Sharepoint]

When I open a dialog for an EditFrom and use the « Delete Item » button from the ribbon, then the main page is redirected to the related Sharepoint list. This behavior is very bad for the user experience.

To change it I used the below Javascript code:

// replace the Delete Item default action when into a popup
$(document).ready(function() {
  // if it's in a popup
  if (window !== window.top) {
    $('a[id$="_toolBarTbl_RptControls_diidIODeleteItem"]').attr("href","javascript:commonDeleteItem(); return false")
  }
})
// now when clicking on the Delete item it will call my own function
// here I use http://aymkdn.github.io/SharepointPlus/ to show a waiting message and to delete the current item, and then close the modal
function commonDeleteItem() {
  $SP().waitModalDialog("Deleting...");
  $SP().list("{"+WPQ2FormCtx.ListAttributes.Id+"}").remove({ID:GetUrlKeyValue("ID")}, {
    after:function() {
      $SP().closeModalDialog();
      $SP().closeModalDialog(2);
    }
  })
}
