Create login button

inkdropmedia

Hey guys I've been having an issue creating a log in button...

I'm using the custom HTML page in the Admin area and wanted to add a "login button" on that HTML... When I look at the code I see there is a script call on the button, but I don't know what the listening event is to make the modal pop up?

Any thoughts on how to create a button that opens the login modal?

Here is the button code I have:

<div class="tbutton">
<button class="Button Button--primary IndexPage-newDiscussion hasIcon" itemclassname="App-primaryControl" type="button" value="click" onclick="doFunction();" title="Log In"><i class="icon fa fa-edit Button-icon"></i><span class="Button-label">TEST Button</span></button>
</div>

Thanks!
