Question

I have an example, a kendo ui grid is added with Backbone.js. In the kendo ui grid I have a buttons to remove rows, but the buttons don’t work on mobile devices. If I press a button repeteadly, it sometimes works. Why?
I declare the button in kendoGrid.columns so:

{
command: [{
     name: "destroy",
     text: "Remove",
     className: "ob-delete"
}

To remove a row and do something when button is clicked:

$(document).on("click", ".grid tbody tr .ob-delete", function (e) {
    var item = grid.dataItem($(this).closest("tr"));
    var check = confirm("Delete");
    if (check) {
        grid.removeRow($(this).closest("tr"));
    }
}); 

Full example

Edit:

I use the kendo ui version: 2012.3.1114

Mobile and click event are not best of friends!

In this code you are adding click on the Html element having .ob-delete class which will not fire Kendo’s built in click event. Instead, try to implement your delete method as custom command shown in this demo: http://demos.kendoui.com/web/grid/custom-command.html

     $(document).ready(function () {
                var grid = $("#grid").kendoGrid({
                    dataSource: {
                       pageSize: 10,
                       data: createRandomData(50)
                    },
                    pageable: true,
                    height: 260,
                    columns: [
                        { field: "FirstName", title: "First Name" },
                        { field: "LastName", title: "Last Name" },
                        { field: "Title" },
                        { command: { text: "View Details", click: showDetails }, title: " ", width: "140px" }]
                }).data("kendoGrid");

                wnd = $("#details")
                    .kendoWindow({
                        title: "Customer Details",
                        modal: true,
                        visible: false,
                        resizable: false,
                        width: 300
                    }).data("kendoWindow");

                detailsTemplate = kendo.template($("#template").html());
            });

            function showDetails(e) {
                e.preventDefault();

                var dataItem = this.dataItem($(e.currentTarget).closest("tr"));
                wnd.content(detailsTemplate(dataItem));
                wnd.center().open();
            }
        </script>

or if a custom command is not required, try the default delete event as shown in this demo.
