One click to open custom select editor

[stoodin]

Is there any way to make custom select editor to be open just on one click? The way it works now (even in your demo) the first click just shows the drop down the second click opens it.
I am using
editModel: {
           saveKey:$.ui.keyCode.ENTER,
           cellBorderWidth: 1,
           clicksToEdit: 1,
           onBlur: 'save',
            keyUpDown:true},

and the editor:
var usersDropDownEditor2 = function (ui, getUsrUrl, searchParam, wdth, callType) {
   var $inp = ui.$cell.find("select");
       rowData = ui.rowData,
       dataIndx = ui.dataIndx,
       dataCell = rowData[dataIndx];

    if (isStringEmpty(wdth))
       wdth = '300px';

   // alert(wdth);
    $inp.width(wdth);
   
    $.ajax({
       url: getUsrUrl,
       type: callType,
       data: searchParam,
        dataType: "json",
        cache: false,
       success: function(json_arr) {
          var opt = $('<option />'),
             fullDesc, empId;
          
          $inp.append(opt);
          
          $.each(json_arr, function(i,val) {
             opt = $('<option />');
             empId = val.employeeId,
             fullDesc = val.rlfName;
             opt.attr('value', empId).text(fullDesc);
             
               if (dataCell && dataCell == fullDesc) {
                  opt.attr('selected', 'selected');
               }
              
               $inp.append(opt);
           });

       },
        error: function(xhr, error) {
           alert("System Error: " +  xhr.responseText);
        }
    });
};

Currently the select editor can't be opened upon creation, it requires another click to open it, this is the limitation of the browser's inbuilt select list.

ParamQuery Select ( custom select or dropdown list ) would support this and it would be available along with the upcoming version of SDK.
