[luci] command execute twice when click a button

[edwin.voip]

Hi, 

 

I try to add a button on luci, like below:

 

scan = s:option(Button, "_scan", "scan")

scan.inputstyle = "find"

function scan.write(self, section)

            luci.sys.exec("echo test >> /root/lucitest")

end

 

 

when I click this button, it will add two line of test string in lucitest. 

 

Did anyone see the same problem before? 

 

Cheers, 

Edwin
