Pressing cancel button avoids a POST to the server, but the content of the editor is not restored

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set show_buttons to true for a text field:

    $('.list_value').editInPlace({
        field_type: 'text',
        url: '/hey/its/a/url',
        show_buttons: true
    });

2. Click in a .list_value element (any text field instrumented with 
jquery.editinplace, and with show_buttons set to true).
3. Change the value of the text.
4. Click Cancel

What is the expected output? What do you see instead?

I expect the original text to be restored. If I refresh the page, I can confirm 
that the cancelled value was not posted to the server. But, the text I 
cancelled remains visible until I refresh.

What version of the product are you using? On what operating system?

Version 2.2.1. This is running on both OS X (dev) and Ubuntu Linux (staging). 
The environment is Rails 4.0.0, jQuery 2.0.3, jQuery UI 1.10.3, Chrome 30.

Please provide any additional information below.

I traced the problem to around line 385 of the source script. The problem is 
that the text field is not a selector, and this.isDisabledDefaultSelectChoice() 
returns false, so after this.restoreOriginalValue() is called at line 383, 
this.setClosedEditorContent(enteredText) is called 3 lines later. I fixed the 
problem by modifying isDisabledDefaultSelectChoice at line 425:

        isDisabledDefaultSelectChoice: function() {
                return this.settings.field_type != "select" || this.dom.find('option').eq(0).is(':selected:disabled');
        },

Well, that doesn't entirely fix the problem. It seems to break the save as 
well. But that's the crux of the problem, at any rate.

I also seem to be using version 2.3.0, according to the comments in the 
beginning of the file:

A jQuery edit in place plugin

Version 2.3.0

Apologies for the misinformation. I may try backing down to 2.2.1 to see if 
that fixes it too.
