URGENT: Record Producer to open in spModal pop-up window on click of a button.

Hi, 

Can anyone help me how to use spModal to open a record producer inside a record producer. Here is the whole requirement.

I have record producer with a button "Add locations". When a user clicks on the button currently it redirects to a different record producer to Add Location. But I want it to open in the same window as a pop-up rather than redirect.

Here is the script for the button. This is where I want to add the pop-up instead of redirect to new window. 

Widget HTML:

<a ng-href="{{options.href}}" target="_blank" class="btn btn-{{options.color}} m-b" ng-if="data.socialQAEnabled">{{data.buttonMsg}}</a>

Widget Client Controller:

function($element, $timeout) {
	/* widget controller */
	var c = this;
	$timeout(function() {
		$element.find('.btn').css("width", c.options.button_width);
	}, 100);
	console.log(c.options.button_width);
}

Widget Server Script:

data.buttonMsg = gs.getMessage(options.button_text || "Click Here");
data.socialQAEnabled = true;
if (options.href == "?id=sqanda_new_question") {
	data.socialQAEnabled = gs.getProperty('glide.sp.socialqa.enabled') === 'true';
}

The above widget is cloned from the OOB link-button widget.

Also I don't want to create a custom form widget as it's easy to maintain producer logics and scripts inside the producer script/script include.
