Onclick doesn't work on nested menu items

[wazzupSu]

I used w2ui 2.0.x, but I think the problem is relevant for earlier versions as well. I needed to pass the src link to the frame, but the onClick event turned out to be available only in the parent-only menu.

So I did like this
....
{text: 'VPS in 8 countries from $ 5', img: 'hosting', onClick: "iframe.src = 'https://wazzup.su/en/'"},
....

 menu_html + =
                            '<tr index = "' + f + '" style = "' + (mitem.style? mitem.style: '') + '"' + (mitem.tooltip? 'title = "' + w2utils.lang (mitem .tooltip) + '"': '') +
                            'class = "' + bg
                                + (options.index === f? 'w2ui-selected': '')
                                + (mitem.disabled === true? 'w2ui-disabled': '')
                                + (subMenu_dsp! == ''? 'has-sub-menu' + ​​(mitem.expanded? 'expanded': 'collapsed'): '')
                                + '"' +
                            'onmousedown = "if (' + (mitem.disabled === true? 'true': 'false') + ') return;' +
                            'jQuery.fn.w2menuDown (event,' + f + ',' + parentIndex + '); "' +
'onclick = "' + ((! mitem.onClick)? '': mitem.onClick) + '; event.stopPropagation ();' +
                            'if (' + (mitem.disabled === true? 'true': 'false') + ') return;' +
                            'jQuery.fn.w2menuClick (event,' + f + ',' + parentIndex + '); ">' +
                                (subMenu? '<td> </td>': '') + imgd +
                            '<td class = "menu-text" colspan = "' + colspan + '">' + w2utils.lang (txt) + '</td>' +
                            '<td class = "menu-count">' + count_dsp + '</td>' +
                            '</tr>' + subMenu_dsp;

It is very clear to me why such a function has not been implemented earlier. Perhaps this is fraught with some consequences. Correct me, please, if I am missing something.

JS fiddle where problem is demonstrated would be helpful.
