Jquery form value "1" set to "false"

I have a form value that is set to “1”, when I submit the form with Jquery the value in the function is set to “false”! Really scratching my head, must be something simple that I am overlooking or some strange (Lucee?) behavior I don’t know of…

The variable is named “vriend_geenvriend” and in the form and Jquery set to “1”.
In the function I have a cfargument for it.
Then if I cfdump the variable it’s seen as boolean and set to “false”.

Any idea’s?
