I am constructing table with input type text and span with role button inside the . I want to trigger javascript function when user clicked on span with role button. Here is my span
         <th>
            <span data-field=@COLUMN_NAME class="k-filtercell" data-role="filtercell">
                  <span>
                       <input id="COLUMN_NAME" data-bind="value: value" style="width:120px" aria-label="Name" title="Name" data-text-field=@COLUMN_NAME role="textbox"  aria-readonly="false" aria-autocomplete="list" >
                     <span unselectable="on" class="k-icon k-clear-value k-i-close k-hidden" title="clear" role="button" onclick="filterInputBtn();" tabindex="-1"></span>
                   </span>
            </span>
       </th>
I am triggering javascript function
            $(document).ready(function () {
            filterInputBtn = function () {
             var inputHTML = $(this).closest('input').val();
           }
        });
But the click event is not getting triggered. Please let me know how to trigger click event from span with role button
