Unable to add image in datepicker

Question

I am using .timepicker inside .jqGrid with filterToolbar. I want to add an image next to filter bar where the user should see a time when they click an image.

If I just use $(element).timepicker(); then I see the time when I click on filter bar but When I do following, timepicker is not working at all.

$(element).timepicker({
                showOn: "button",
                buttonImage: "https://jqueryui.com/resources/demos/datepicker/images/calendar.gif",
                buttonImageOnly: true,
          });

The same options work with datepicker. What am I missing here? Is this due to jquery.timepicker.js version?

Working Demo

$(function() {
  "use strict";

  $("#grid").jqGrid({
    colModel: [{
      name: "StartRunTime",
      label: "Start Run Time",
      align: "center",
      sorttype: "time",
      formatter: "time",
      searchoptions: {
        dataInit: function(element) {
          $(element).timepicker();
        }
      }
    }],
    data: [{
      StartRunTime: "12:00"
    }],
   
    caption: ".jqGrid Test"
  }).jqGrid('filterToolbar', {
    autoSearch: true
  });
});

Answer 1

thats not valid option, but you can insert image and listener like this

$(document).on("click", ".showCalendar", function(){
  $("#gs_grid_StartRunTime").timepicker('show');
});
$('#gs_grid_StartRunTime').parent()
  .after('<td><img class="showCalendar" src="https://jqueryui.com/resources/demos/datepicker/images/calendar.gif"></td>');

Demo:

$(function() {
  "use strict";

  $("#grid").jqGrid({
    colModel: [{
      name: "StartRunTime",
      label: "Start Run Time",
      align: "center",
      sorttype: "time",
      formatter: "time",
      searchoptions: {
        dataInit: function(element) {
          $(element).timepicker();
        }
      }
    },
    {
					label: "Concept Name",
					name: "ConceptName",
					key: true,
					width: 100,
					align: "center"
				}],
    data: [{
      StartRunTime: "12:00",
      ConceptName: "ABC"
    }],

    caption: ".jqGrid Test"
  }).jqGrid('filterToolbar', {
    autoSearch: true
  });
  $(document).on("click", ".showCalendar", function(){
  	$("#gs_grid_StartRunTime").timepicker('show');
  });
  $('#gs_grid_StartRunTime').parent().after('<td><img class="showCalendar" src="https://jqueryui.com/resources/demos/datepicker/images/calendar.gif"></td>');
  
});

.showCalendar {
	margin: 0px 2px;
	cursor: pointer;
}
