Deprecated calls to sendAction

[Karanval]

Getting the next warnings in the browser:

• DEPRECATION: You called <host@component:ember-selectize::ember242>.sendAction("on-init") but Component#sendAction is deprecated. Please use closure actions instead. [deprecation id: ember-component.send-action]

• DEPRECATION: You called <host@component:ember-selectize::ember242>.sendAction("on-focus") but Component#sendAction is deprecated. Please use
  closure actions instead. [deprecation id: ember-component.send-action]

• deprecate.js:102 DEPRECATION: You called <host@component:ember-selectize::ember242>.sendAction("on-blur") but Component#sendAction is deprecated. Please use closure actions instead. [deprecation id: ember-component.send-action]

And I'm sure there are a couple more around.
