Change Signature Algorithm from groovy script

I trying to change the Signature Algorithm for Outgoing WS-Security Configurations from the groovy script.
Here is my code:

import com.eviware.soapui.support.XmlHolder

project = testRunner.testCase.testSuite.project
WssC = project.getWssContainer();
outWss = WssC.getOutgoingWssByName('outCrypto')
config = outWss.getConfig()
configSignature =  config.getEntryList()[0].getConfiguration()

holder = new XmlHolder(configSignature)

holder.setNodeValue('signatureAlgorithm','http://www.w3.org/2001/04/xmldsig-more#rsa-sha256')
//holder.setNodeValue('signatureAlgorithm','http://www.w3.org/2000/09/xmldsig#rsa-sha1')

holder.updateProperty(true)
config.getEntryList()[0].setConfiguration(holder.getXmlObject())
config.set(config)
outWss.updateConfig(config)
WssC.resetConfig(WssC.getConfig())

 After running the code, the signature does not change. In the WS-Security Configurations window still was an old algorithm, but when I save and reload the project the algorithm was changed according to what was in the script.

How to change the algorithm so that the change is immediate?
