Issue in Auto suggest and auto complete of oj-input-text

Content

I want to implement auto suggest and auto complete on oj-input-text. I have used the below code in my html page:

<oj-input-text id="avSearchbox" autocomplete="off"  clear-icon="conditional" on-focus="[[$listeners.avSearchboxFocus]]" on-keydown="[[$listeners.avSearchboxKeydown]]" on-keypress="[[$listeners.avSearchboxKeypress]]" on-keyup="[[$listeners.avSearchboxKeyup]]" on-click="[[$listeners.avSearchboxClick]]"></oj-input-text>

I am calling an action chain on the above events in which i am using a module function. To get the details of the selected text from the auto suggest, I am using event.getSource which is giving error as it is not able to detect the type of event in the module function. Please suggest a way or any reference how we can pass the event details to the module function of the action chain.
