Resolve Issue 78 : DropdownItem Click Event Parameter Type Issue

[codersyntax]

Change dropdown item to return the component instead of just the label to better match the ix core library functionality

💡 What is the current behavior?

Currently, the Dropdown Item component OnClickEvent returns the label string property and does not match the current IX Core functionality

GitHub Issue Number: #78

🆕 What is the new behavior?

With the changes, the Dropdown Item component OnClickEvent returns the DropdownItem component itself allowing access to more properties and matches the functionality of the IX Core.
