This event is triggered when a user searches an item in the drop-down list either by typing in the textbox or by calling the search method of wijcombobox.

$(function () {
    // Set search event handler function
    $(".selector").wijcombobox({
        search : function (e, data) {
     
        }
    });
});

search = function ( 
   e : jQuery.Event,
   data : ISearchEventArgs
) { };
