onChange function

[ataxel]

I'm using cmsms v 1.3.1 with TinyMCe 2.4.0

I have a define javascript function that is needs to have this kind code to make the result appears in a div ID...

Code: Select all

 <input type="checkbox" onChange="changeValueChk(this, 100)"> 

The problem is that everytime I save the page, even with HTML, tinyMCE erase the 

Code: Select all

 onChange="changeValueChk(this, 100) 

What can I do to resolve this ? I try to put it between literal tag without success.

Thank you.
