While trying to determine what was slowing down my autocomplete text box, I noticed that every time the user types in the target text box the number of event listeners would go up. It looks like autocomplete (or the widget factory?) is adding duplicate "remove" events to the target. This can be reproduced by adding the following line to the default autocomplete example at ​https://jqueryui.com/autocomplete/ .

response: function (e, ui) {
        console.log( jQuery._data( $("#tags")[0], "events" ) );
      }

When looking at the results in chrome's tools I can see the number of event listeners go up every time the the user types in the target text box.

Object {remove: Array[3], keydown: Array[1], keypress: Array[1], input: Array[1]...
Object {remove: Array[5], keydown: Array[1], keypress: Array[1], input: Array[1]...
Object {remove: Array[7], keydown: Array[1], keypress: Array[1], input: Array[1]...
Object {remove: Array[9], keydown: Array[1], keypress: Array[1], input: Array[1]...

Hi, I have integrated the autocomplete component for which I have set autoFocus=true in order to have the first item highlighted in the dropdown list of filtered results.

Quick note here: in general the "highlighted" item is selected when user clicks on it or press tab or enter.

Issue: When the first item is highlighted after expanding the dropdown, if the user presses Enter or Tab, the item is not selected

Steps to reproduce:

1. Click on the arrow to expand
2. Press tab

Expected result: Highlighted item (in that case the first one) should become selected

Thank you for considering my request

Following up on case #15049:

I have encountered a similar problem in my application, where selectmenu("refresh") gets slower and slower. Please check ​http://jsbin.com/nibibohigi/edit?html,js,output for a basic example. I have seen that the

this.bindings = this.bindings.add( element ) 

in the _on method in $.Widget.prototype causes the problem. The list of bindings increases on each refresh - it ends up containing thousands of entries.
