AW.UI.Checkbox issue in iPad

Hello friends,

I am using AW.UI.Checkbox in my code, issue is checkbox is not populating on IPad

Please give valuable solution

How to reproduce this? Do you see the same issue in any example file in the package?

No, Actually I had created a AW.UI.Checkbox for populating a AW Grid.
My work is going fine on all browsers, but facing a issue on Ipad. (Not able to see check boxes on Ipad)

I am using this type of code in javascript for creating a check box in AW Grid.

var objGridHeaderChkBox = new AW.UI.Checkbox;
objGridHeaderChkBox.setEvent("onclick",objGridToggleAllChkBoxes);
objGridHeaderChkBox.setControlValue(false);
objGridHeaderChkBox.setStyle('position', 'relative'); // use for set checkbox margin
objGridHeaderChkBox.setStyle("font-family", "'Helvetica','Arial',sans-serif ");
objGridHeaderChkBox.setStyle('left', '-6px !important' ); // use for set checkbox margin
objGridHeaderChkBox.setStyle('margin-left', '-11px' );
objGridHeaderChkBox.setStyle('margin-right', '-6px' );
objGridHeaderChkBox.setStyle('padding-left', '27px' );
