How do I filter features out of ArcGISDynamicMapServiceLayer by field?

Hello,

I have an app utilizing a ArcGISDynamicMapServiceLayer which I need to return images with features filtered out based on data fields in each layer. While I managed to figure out how to do this, it seems to be breaking layer visibility toggling. The code I am using to accomplish this is below:

ArcGISDynamicMapServiceLayer {
    id : dynamicLayer
    credentials : config.tdnArcGisUserCreds
    url : activeClient.dynamicMapServiceUrl
    Component.onCompleted : {
        app.dynamicLayer = dynamicLayer
    }
    onStatusChanged : {
        if (status == Enums.LayerStatusInitialized) {
            sidePanel.initLayers();
            for (var i = 0, l = dynamicLayer.dynamicLayerInfos.length; i < l; i++) {
                dynamicLayer.dynamicLayerInfos.definitionExpression = "FIELD = 'VALUE'";
            }
        }
    }
}

This results in filtered dynamic images, but completely disabled layer toggling. This also seems to send out an additional request for each layer every single time a layer is toggled. Despite that, the toggling of the layers doesn't alter the returned image.

Does anyone know what I'm doing wrong?
