how to add new property to ng2-smart-table

i have added getValueFromParent

ERROR Error: Uncaught (in promise): Error: Template parse errors:
Can't bind to 'getValueFromParent' since it isn't a known property of 'ng2-smart-table'.
1. If 'ng2-smart-table' is an Angular component and it has 'getValueFromParent' input, then verify that it is part of this module.
2. If 'ng2-smart-table' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.
3. To allow any property add 'NO_ERRORS_SCHEMA' to the '@NgModule.schemas' of this component. ("

how can i fix this
