在淘汰赛数据绑定属性绑定不起作用？

Question

I have a problem When clicking link( tag).it contains data-bind,by using attr binding i am giving the url,and at the same time using click binding My problem is click binding is working but not redirect the url by attr binding . I try this code..

 viewModel.printbill = function () {
    var dta = ko.utils.arrayFilter(viewModel.Bills(), function (item) {
        return item.BillID == viewModel.BillID();
    });
    if (dta != null) {
        var data = {
            List: dta
        }
        localStorage.setItem('SelectedBill', JSON.stringify(data));
    }
};

<a target="_blank" title="" data-bind='attr: {href:"@Href("~/billing/BillPrint") "},click:printbill'> when clicking this link i have a click binding:printBill,which is used to select a specific id from the button clik and map into localstorage ...all things are going good..but ..i cant redirect the screen to another tab.

If you have both a click binding and an href on a link then you need to return true from the binding for the href to be followed - think of it as being able to cancel the click (and therefore the navigation).

 viewModel.printbill = function () {
    var dta = ko.utils.arrayFilter(viewModel.Bills(), function (item) {
        return item.BillID == viewModel.BillID();
    });
    if (dta != null) {
        var data = {
            List: dta
        }
        localStorage.setItem('SelectedBill', JSON.stringify(data));
    }
    return true; // <---- here
};

而不是使用链接使用按钮来重定向并单击
