you need to use virtual attributes and callbacks to achieve this.  Read on
attr_accessor
and http://api.rubyonrails.org/classes/ActiveRecord/Callbacks.html

Have you read on callbacks and virtual attributes?

First you need to determine which area is going wrong.
Firstly is the html that is being generated what you expect.  Have a
look at the html of the page (using View > Page Source or similar in
your browser).  Does that look ok?
Secondly perhaps the data is not being sent to the server correctly.
Look in log/development.log to check that the data is being passed and
the correct action is being called.
Thirdly perhaps there is an error in the action in the controller.
Have a look at the Rails Guide on Debugging and it will show you
techniques you can use to debug your code.

It is really better to only have one question at a time, otherwise the
answers will get confusing.

Did you type that last line, or copy and paste from your code?

:Status

or

:status

???

Ruby variables are usually snake-case. Classes are camel-case. Which is this?

Just concatenate them in the controller, what is the problem?
