How to do a mouse click event on tableview JavaFX

I have a tableview with a model class for it. The table view shows all groups that a user can join and I would like to have a mouseclick event on the row of a tableView that a user clicks. This will change a text on a label to say if there is space in the group or not.

The problem that i am getting is "Caused by: javafx.fxml.LoadException: Error resolving onMouseClicked='#clickItem', either the event handler is not in the Namespace or there is an error in the script." I am using a scene builder and have declared the method to "On Mouse Clicked" and still getting the error.

Would be helpful if you can tell me a solution to be able to do this or fix the error. Thanks in advance.

public void showAvailability(MouseEvent event) { 

    selected = groupsTable.getSelectionModel().getSelectedItem();
    boolean checkAvailability  = checkSpaceInGroup(selected);

    if(checkAvailability){
        availabilityStatus.setText("Space in Group");
        availabilityPane.setStyle("-fx-background-color: #" + "388e3c ");
    }
    else{
        availabilityStatus.setText("NO SPACE");
        availabilityPane.setStyle("-fx-background-color: #" + "ffcdd2 ");

    }
}

You might have imported wrong library: (not sure without looking at the whole code)

import java.awt.event.??

instead of:

import javafx.event.??

However you can create an event from your Initialize method, on controller class, like this: 

groupsTable.setOnMouseClicked((MouseEvent event) -> { 
 //your code goes here
}

In this case, MouseEvent is imported using:

import javafx.scene.input.MouseEvent;

Hope it helps!
