Try this –
$(document).on("click", "#submit_btn", function(event){
alert( "GO" );
});
Or this –
$(document).delegate("#submit_btn", "click", function(event){
alert( "GO" );
});
If you are using an older version of jQuery you may have to use the live method instead.
Live method (use this only if you have to)
$("#submit_btn").live("click", function(event){
alert( "GO" );
});
I’m fairly certain that one of these 3 methods above will solve your issue. The reason your event handler doesn’t work is because your submit_btn element doesn’t exist at the time your event handler is evaluated. The above 3 handlers I gave you will work on a submit_btn element that exists now and in the future.

Here is a jsfiddle that works – http://jsfiddle.net/GqD4f/8/

I made a jsfiddle using the approach you had in your post and it works – http://jsfiddle.net/CR3bM/1/
Are you not putting your event handler in DOM ready?
