==Syntax==
<syntaxhighlight lang="lua">
bool Button:RemoveOnTextChanged ( function func )
</syntaxhighlight>

===Required Arguments===
*'''func:''' the function you want to remove from the list of functions triggered when text changes

===Returns===
*'''true''' if function was removed successfully
*'''false''' otherwise

==Example==
This example creates a button. The button has two functions attached to it, one is triggered when user clicks the button (to change text on the button) and the other one is triggered when the text has changed then the function is detached and no longer triggered.
<syntaxhighlight lang="lua">
addEventHandler ( "onClientResourceStart", getResourceRootElement( getThisResource( ) ),
function( )
--create a button object
local button = Button:Create( 0.7, 0.1, 0.2, 0.1, "Hello", true );

-- and attach a function to the button which changes its text
button:AddOnClick( changeMyText );

-- add myTextHasChanged to the list of triggered functions when text changes
button:AddOnTextChanged( myTextHasChanged );
end
)

--setup a function to change the text
function changeMyText ( )
local text = button:Text( ) --get the text from the button
if text == "Hello" then
-- if text of button was "Hello", change it to "World!"
button:Text( "World!" );
button:Enabled( false );
end
end

function myTextHasChanged( btn, oldText, newText )
-- if new text is "World!" then set a timer which will change it back to old text (in this case "Hello"),
-- enable the button and remove this function from the stack
if newText == "World!" then
setTimer( btn:Text, 2500, 1, oldTex );
setTimer( btn:Enabled, 2500, 1, true );
end
btn:RemoveOnTextChanged( myTextHasChanged );
end

</syntaxhighlight>
