When Bootstrap Select initializes  it ll build a set of custom divs that run alongside the original  lt select gt  element and will typically synchronize state between the two input mechanisms     Which is to say that one way to handle events on bootstrap select is to listen for events on the original select that it modifies  regardless of who updated it   Solution 1 - Native Events  Just listen for a change event and get the selected value using javascript or jQuery like this        select   on  change   function e     console log this value                this options this selectedIndex  value                  this  find  option selected   val             NOTE  As with any script reliant on the DOM  make sure you wait for the DOM ready event before executing  Demo in Stack Snippets    x000D   x000D    function     x000D   x000D       select   on  change   function e   x000D      console log this value  x000D                  this options this selectedIndex  value  x000D                    this  find  option selected   val      x000D        x000D     x000D      x000D   lt link href    cdnjs cloudflare com ajax libs twitter-bootstrap 3 3 2 css bootstrap css  rel  stylesheet   gt  x000D   lt link href    cdnjs cloudflare com ajax libs bootstrap-select 1 12 4 css bootstrap-select css  rel  stylesheet   gt  x000D   lt script src    cdnjs cloudflare com ajax libs jquery 2 1 3 jquery js  gt  lt  script gt  x000D   lt script src    cdnjs cloudflare com ajax libs twitter-bootstrap 3 3 2 js bootstrap js  gt  lt  script gt  x000D   lt script src    cdnjs cloudflare com ajax libs bootstrap-select 1 12 4 js bootstrap-select js  gt  lt  script gt  x000D   x000D   lt select class  selectpicker  gt  x000D     lt option val  Must  gt  Mustard  lt  option gt  x000D     lt option val  Cat   gt  Ketchup  lt  option gt  x000D     lt option val  Rel   gt  Relish   lt  option gt  x000D   lt  select gt  x000D   x000D   x000D    Solution 2 - Bootstrap Select Custom Events  As this answer alludes  Bootstrap Select has their own set of custom events  including changed bs select which      fires after the select s value has been changed  It passes through event  clickedIndex  newValue  oldValue    And you can use that like this      select   on  changed bs select          function e  clickedIndex  newValue  oldValue        console log this value  clickedIndex  newValue  oldValue        Demo in Stack Snippets    x000D   x000D    function     x000D   x000D       select   on  changed bs select    x000D          function e  clickedIndex  newValue  oldValue    x000D        console log this value  clickedIndex  newValue  oldValue  x000D        x000D   x000D      x000D   lt link href    cdnjs cloudflare com ajax libs twitter-bootstrap 3 3 2 css bootstrap css  rel  stylesheet   gt  x000D   lt link href    cdnjs cloudflare com ajax libs bootstrap-select 1 12 4 css bootstrap-select css  rel  stylesheet   gt  x000D   lt script src    cdnjs cloudflare com ajax libs jquery 2 1 3 jquery js  gt  lt  script gt  x000D   lt script src    cdnjs cloudflare com ajax libs twitter-bootstrap 3 3 2 js bootstrap js  gt  lt  script gt  x000D   lt script src    cdnjs cloudflare com ajax libs bootstrap-select 1 12 4 js bootstrap-select js  gt  lt  script gt  x000D   x000D   lt select class  selectpicker  gt  x000D     lt option val  Must  gt  Mustard  lt  option gt  x000D     lt option val  Cat   gt  Ketchup  lt  option gt  x000D     lt option val  Rel   gt  Relish   lt  option gt  x000D   lt  select gt  x000D   x000D   x000D
