I'm trying to use jquery to change a dropdown value in SharePoint page and when the dropdown value is changed I want to fire another event.  I can change the dropdown value using jquery but it does not fire the next event when it is changed.  So i'm missing something.  Any advice greatly appreciated.

the fiddle is here:  http://jsfiddle.net/vhabhsrosed/Ljkb2574/4/

the code example:

//SET CODE TO FUNCTION WHEN ON COMMITTEE MEETING FORMS PAGE
 
$(document).ready(function(){

var xAgenda = "Safety";
//alert("COMMITTEE = " + xAgenda);
var xCT = "Committee Action - " + xAgenda;
alert(xCT);

$("SELECT[title*='Content Type']").change(function(){
alert("ive changed");
});

$("SELECT option").filter(function () { return $(this).html() == xCT; }).prop('selected', true);   //USE TO CORRECT WELCOME PAGE BOUNCE BACK ISSUE?
};
            
              }); //end ready
