    Hi,

    Been working a lot with Web components on a new project I am working on, now trying to develop a mobile app, so switching over to Kendo Mobile.

    I want to add a button to selected items in a ListView using a template, which I can do easily enough, and I have added data-bind attribute with a value of "click: onDelete". The button appears correctly in the items I want it to appear in.

    When a user clicks on the button I want to run the relevant code in my viewModel passing in the details of the item for which the button was clicked so I can do some further processing.

    How do I do this - is there any example somewhere of how this works because I am unable to get the button click to trigger a function call in my viewModel and pass in teh relevant item details

    Many thanks in advance

    OK so I have made some progress in that I have added a detailbutton to my template and am able to trigger the click event for this which is a start...

    I use the code to pick the item ID which I can then use for my next stage

    var item = e.button.closest("li"); //get the item
    alert("ID= " + item.data("uid"));

    However the ID I receive is not the ID from my datasource, rather it is some randomly generated GUID I assume by the Kendo Framework.

    The schema part of my datasource code looks like this:

    schema: {
             model:
             {
                 id: "ID"
             },
             data: "List",
             errors: "APIError",
             total: "TotalRowCount"
         }

    The data I am using is contained in List, and the name of the field that contains the ID is called ID, so why does it not set teh data-uid correctly to the value I require?

    Hi Huw,

    The corresponding data item is accessible in the data field of the button event handler parameter. Please check this example for what I mean.
