Add, Edit Popup position in IPAD

[Bertha]

When I clicked Add or Edit button of Grid, it is centered correctly in computer.  When it is in IPAD, the popup will go to the top right corner.  I guess it could be bootstrap or accordion container of my settings.  Is there a way I can tell the popup of Add window to show in the middle or on top left corner?

Thanks.

sorry, I already find a solution in the web.

edit: function (e) {
var editWindow = this.editable.element.data("kendoWindow");
editWindow.center();
