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);
    }
  })
}
