Adjusting keyboard size in angular module config doesn't work

[MidanRayam]

This doesn't work:

.config(['VKI_CONFIG', function(VKI_CONFIG) {
    VKI_CONFIG.size = 3;
  }])`

This fixes it for me:
config.size = config.size >=1 && config.size <= 5 ? config.size : VKI_CONFIG.size;

In:

.service('ngVirtualKeyboardService', ['VKI_CONFIG', function(VKI_CONFIG) {
    /*globals VKI */
    return {
        attach: function(element, config, inputCallback) {
            config = config || {};
            config.i18n = config.i18n || VKI_CONFIG.i18n;
            config.kt = config.kt || VKI_CONFIG.kt;
            config.relative = config.relative === false ? false : VKI_CONFIG.relative;
            config.keyCenter = config.keyCenter || VKI_CONFIG.keyCenter;
      config.size = config.size >=1 && config.size <= 5 ? config.size : VKI_CONFIG.size;
            config.sizeAdj = config.sizeAdj === false ? false : VKI_CONFIG.sizeAdj;
            config.customClass = config.customClass || VKI_CONFIG.customClass;

            var vki = new VKI(config, VKI_CONFIG.layout, VKI_CONFIG.deadkey, inputCallback);
            vki.attachVki(element);
        }
    };
}])```
