Search problem

Hello,

I have a probem with the search module. When I edit placeholder or add button or change the label, nothing change.
After some of tests, I have found the problem, it's the template because with the default joomla template, i have no problem.
Can you help me to solve this problem please?

Our search module is an ajax based search module.
If you want a basic search module, please take the Joomla search module and publish this module on module position > suídebar-b or any other module psoition.
But not at search module position
